UCD90120/4 EVM GUI Setup
3 UCD90120/4 EVM GUI Setup
3.1 UCD90120/4 EVM GUI Installation
The UCD90120 and UCD90124 EVMs use the Texas Instruments Fusion Digital Power Designer
graphical user interface (GUI) which may be downloaded from the following web site:
http://focus.ti.com/docs/toolsw/folders/print/fusion_digital_power_designer.html
Place the TI-Fusion-Digital-Power-Designer-zip file in a known location on the PC. Unzip the
TI-Fusion-Digital-Power-Designer-zip file.
Double click the unzipped TI-Fusion-Digital-Power-Designer-exe file. Proceed through the installation by
accepting the installer prompts and the license agreement. Accept the GUI suggested default PC
installation locations to complete the install.
Once the GUI completes the installation it will start. The first time the GUI is launched on a particular PC
the user may be prompted to select a device. Choose UCD9xxx. Afterwards, the GUI may be closed.
Note that the TI-Fusion-Digital-Power-Designer v1.6.105 was used for the examples to be shown later in
the document.

5 Description
The following paragraphs describe the UCD90120/4 EVM functionality and operation.
5.1 Communication Interfaces
Several communication interfaces to the UCD90120/4 are provided on the EVM.
5.1.1 USB Interface
An onboard USB to PMBus interface is provided through the USB Input (J3) connector. D56 provides USB
attach status. The presence of USB power at J3 activates buffer circuitry which gives control of the PMBus
to the on board circuitry. The absence of USB power at J3 gives PMBus control through the Expansion
PMBus (J77) connector.
5.1.2 PMBus
Standard PMBus interface is provided to the UCD90120/4 through the J77 connector when the on EVM
USB-PMBus interface is not used. PMBus addressing is set using the J18 jumper block for ADDRSENS1
and ADDRSENS0 respectively. ADDRx=8 and ADDRx=5 positions for each are provided. The EVM
comes with PMBus address set to 101 decimal.
PMBus Address (decimal) = 12 × ADDR1 + ADDR0 jumper block setting.
5.1.3 JTAG
Standard JTAG programming interface is provided to the UCD90120/4 through the J9 connector. Install
J6, J7, J11, and J12 jumpers and ensure that rail 9-12 enable jumpers (J47, J53, J59, J65) are removed
when using the JTAG interface.
Description
5.2 Power
5.2.1 Input Power
The 12VDC EVM input power is provided through J1 (standard DC jack) or J2 (screw jack). A wall or
laptop adapter with 500mA (UCD90120EVM) or 2000mA (UCD90124EVM running a fan) capability and
2.5mm I.D. x 5.5mm O.D. x 9.5mm DC jack can power the EVM. Reverse voltage protection and inrush
limiting is provided for 12VBUS. The 12VBUS signal is distributed for fan power and Local 3.3V supply.
5.2.2 5VBUS
5VBUS is derived from 12VBUS and provides the input voltage for rails 1-12. D5 will illuminate when
5VBUS is present.
5.2.3 L3P3V
L3P3V is derived from 5VBUS and provides a general purpose 3.3V supply for the common onboard
functions. The L3P3V jumper (J4) is installed to provide a connection to the 3P3V node.
5.2.4 V33D
The V33D node is connected to the UCD90120/4 digital and analog supply pins. V33D can be sourced by
3P3V or Local V33D using the J5 jumper. D9 will illuminate when V33D is present.
5.2.5 Local 3.3V
The UCD90120/4 can be powered from 12VBUS using the local V33D supply. Install J13 (12VB) and
ensure J5 is installed in the LV33D position to use the local regulator.

Description
5.2.6 Local USB
When the local 12V power supply source is not available, a subset of EVM functionality is available using
only power from the local USB source (3P3V_USB). Install J8 (3.3VUSB) and remove J4 when this
operation is desired. Communication to the UCD90120/4 is possible but power supply sequencing and
operation is not.
5.3 Test/Debug and Status
5.3.1 GPIO Expansion
J73 and J74 provide EVM to system board expansion capability as well as an HP type logic analyzer
interface.
5.3.2 Status LEDs
Visual status information for the GPI, GPIO, and PMBus signals (control and alert) is provided. Logic high
at GPI1-4 or GPIO1-22 will illuminate the associated LED. The GPIO status LEDs can be enabled (EN) or
disabled (EN bar) through the use of S10 to prevent the LED bias from affecting the logic state of the
GPIO signal during device reset.
5.4 Digital I/O Terminations
5.4.1 General Purpose Input/Output Terminations

5.5.2 MON2, MON3, MON12 and MON13
MON2 can be sourced by the onboard rail (L2), an external (E2) or the on board temperature sensor (T1)
voltage. MON3 can be sourced by the onboard rail (L3), an external (E3) or the on board current monitor
(C1) voltage. MON12 can be sourced by onboard rail (12L), an external source (12E) or the onboard fan
temperature potentiometer input (TEMP MON) voltage. MON13 can be sourced by the V33D or 12VBUS
voltage.
5.5.3 Monitor Scaling
For the external monitor jumper positions (E1-E4), the external supply can be scaled by a selectable factor
of 2 for monitoring external voltages up to 5V or 6 for monitoring external voltages up to 15V. For MON13,
the scale factor is 6 for the 12VB position and 2 for the V33D position. For all other MON jumper positions,
the scale factor is 2.
5.5.4 Monitor Fault Injection
Under voltage or over voltage faults can be injected on MON 5–MON12 through the use of on board

Description
5.10 Fan Interface
The UCD90124 provides support for up to four fans. The UCD90124EVM provides a single fan interface
from J66. The UCD90124EVM interface can support three fan types including 2-wire, 3-wire, and 4-wire.
The FAN connector has four terminals (12V, GND, Tach, and PWM).
5.10.1 Fan Tach Input
The fan tach signal is an input to the UCD90124 providing an indication of fan speed based on signal
frequency. The EVM Tach input signal is conditioned prior to being connected to the UCD90124 and can
interface with either a 3.3V or 5V signal using J72. Install a shunt in the TACH position of J67 to connect
the conditioned signal to the UCD90124. The TACH signal at J66-2 is inverted by the conditioning circuitry
prior to J67.
5.10.2 Fan PWM Output
The fan PWM signal is an output from the UCD90124 providing fan speed control using a pulse width
modulated signal. The UCD90124 output signal can come from either PWM1 (J67 in the PWM position) or
FPWM5 (J70 in the FPWM5 position). The PWM1 or FPWM5 output signal can directly drive the fan PWM
input (four wire fan with J68 in the 4W position) or be conditioned prior the fan PWM input (two or three
wire fan with J68 in the 2/3W position). When J68 is in the 2/3W position, the PWM signal at J66-3 can
drive or modulate the ground of a two or three wire fan. When J68 is in the 2/3W position, the PWM signal
at J66-3 can provide a 3.3V, 5V, or 12V level PWM signal with appropriately installed shunts on J69 for
use with four wire fans. When J68 is in the 2/3W position, the PWM1 or FPWM5 signal at J70 is inverted
by the conditioning circuitry prior to J66-3.
www.ti.com
5.10.3 Fan Temperature Simulation
An onboard potentiometer (TEMP MON) can be used to simulate analog temperature when used in
conjunction with the fan interface for fan speed control. The potentiometer voltage can be monitored at
TP54 (TEMP MON) through MON12. Install a shunt in the 12E position of J61 and install J71 (EVR12).
The potentiometer voltage can be varied from 0 to approximately 4.2V. This voltage is scaled by 2 before
being sampled at MON12.

Layout Guidelines, EVM Schematic, and Assembly Drawings
7 Layout Guidelines, EVM Schematic, and Assembly Drawings
7.1 Layout Guidelines
Thermal pad
The thermal pad provides a thermal and mechanical interface between the device and the printed circuit
board (PCB). While device power dissipation is not of primary concern, a more robust thermal interface
can help the internal temperature sensor provide a better representation of PCB temperature. Connect the
exposed thermal pad of the PCB to the device VSS pins and provide at least a 4 × 4 pattern of PCB vias
to connect the thermal pad and VSS pins to the circuit ground on other PCB layers.
Supply voltage decoupling
Provide power supply pin bypass to the device as follows:
• 0.1µF, X7R ceramic in parallel with 0.01µF, X7R ceramic at pin 47 (BPCAP)
• 0.1µF, X7R ceramic in parallel with 4.7µF, X5R ceramic at pin 44 (V33D)
• 0.1µF, X7R ceramic at pin 7 (V33DIO)
• 0.1µF, X7R ceramic in parallel with 4.7µF, X5R ceramic at pin 46 (V33A)
Digital output signals
Depending on use and application of the various GPIO signals used as digital outputs, some impedance
control may be desired to quiet fast signal edges. For example, when using the FPWM pins for fan control
or voltage margining the pin will be configured as a digital clock signal. Route these signals away from
sensitive analog signals. It is also good design practice to provide a series impedance of 20–33 Ω at the
signal source to slow fast digital edges.
PMBus clock and data
Route PMBUS_CLK and PMBUS_DATA in a careful fashion away from sensitive analog signals. Provide
a series impedance of 20–33 Ω at the signal source.
7.2 EVM Schematic
The searchable PDF of the schematic is appended to this User's Guide.
7.3 Assembly Drawings
The assembly drawings are appended to this User's Guide. The topside and bottomside component
layouts are searchable.

equipment in other environments may cause interference with radio communications, in which case the user at his own expense
will be required to take whatever measures may be required to correct this interference.
EVM Warnings and Restrictions
It is important to operate this EVM within the input voltage range of 0 V to 20 V and the output voltage range of 0 V to 5 V .
Exceeding the specified input range may cause unexpected operation and/or irreversible damage to the EVM. If there are
questions concerning the input range, please contact a TI field representative prior to connecting the input power.
Applying loads outside of the specified output range may result in unintended operation and/or possible permanent damage to the
EVM. Please consult the EVM User's Guide prior to connecting any load to the EVM output. If there is uncertainty as to the load
specification, please contact a TI field representative.
During normal operation, some circuit components may have case temperatures greater than 85°C. The EVM is designed to
operate properly with certain components above 85°C as long as the input and output ranges are maintained. These components
include but are not limited to linear regulators, switching transistors, pass transistors, and current sense resistors. These types of
devices can be identified using the EVM schematic located in the EVM User's Guide. When placing measurement probes near
these devices during operation, please be aware that these devices may be very warm to the touch.

IMPORTANT NOTICE
Texas Instruments Incorporated and its subsidiaries (TI) reserve the right to make corrections, modifications, enhancements, improvements,
and other changes to its products and services at any time and to discontinue any product or service without notice. Customers should
obtain the latest relevant information before placing orders and should verify that such information is current and complete. All products are
sold subject to TI’s terms and conditions of sale supplied at the time of order acknowledgment.
TI warrants performance of its hardware products to the specifications applicable at the time of sale in accordance with TI’s standard
warranty. Testing and other quality control techniques are used to the extent TI deems necessary to support this warranty. Except where
mandated by government requirements, testing of all parameters of each product is not necessarily performed.
TI assumes no liability for applications assistance or customer product design. Customers are responsible for their products and
applications using TI components. To minimize the risks associated with customer products and applications, customers should provide
adequate design and operating safeguards.
TI does not warrant or represent that any license, either express or implied, is granted under any TI patent right, copyright, mask work right,
or other TI intellectual property right relating to any combination, machine, or process in which TI products or services are used. Information
published by TI regarding third-party products or services does not constitute a license from TI to use such products or services or a
warranty or endorsement thereof. Use of such information may require a license from a third party under the patents or other intellectual
property of the third party, or a license from TI under the patents or other intellectual property of TI.
Reproduction of TI information in TI data books or data sheets is permissible only if reproduction is without alteration and is accompanied
by all associated warranties, conditions, limitations, and notices. Reproduction of this information with alteration is an unfair and deceptive
business practice. TI is not responsible or liable for such altered documentation. Information of third parties may be subject to additional
restrictions.
Resale of TI products or services with statements different from or beyond the parameters stated by TI for that product or service voids all
express and any implied warranties for the associated TI product or service and is an unfair and deceptive business practice. TI is not
responsible or liable for any such statements.
TI products are not authorized for use in safety-critical applications (such as life support) where a failure of the TI product would reasonably
be expected to cause severe personal injury or death, unless officers of the parties have executed an agreement specifically governing
such use. Buyers represent that they have all necessary expertise in the safety and regulatory ramifications of their applications, and
acknowledge and agree that they are solely responsible for all legal, regulatory and safety-related requirements concerning their products
and any use of TI products in such safety-critical applications, notwithstanding any applications-related information or support that may be
provided by TI. Further, Buyers must fully indemnify TI and its representatives against any damages arising out of the use of TI products in
such safety-critical applications.
TI products are neither designed nor intended for use in military/aerospace applications or environments unless the TI products are
specifically designated by TI as military-grade or "enhanced plastic." Only products designated by TI as military-grade meet military
specifications. Buyers acknowledge and agree that any such use of TI products which TI has not designated as military-grade is solely at
the Buyer's risk, and that they are solely responsible for compliance with all legal and regulatory requirements in connection with such use.
TI products are neither designed nor intended for use in automotive applications or environments unless the specific TI products are
designated by TI as compliant with ISO/TS 16949 requirements. Buyers acknowledge and agree that, if they use any non-designated
products in automotive applications, TI will not be responsible for any failure to meet such requirements.
