1Description
The complete two-board TPS92518EVM solution provides a dual-channel, high-brightness LED current
regulator which is configurable via a graphical user interface (GUI). It is designed to operate with an input
voltage in the range of 6.5–65 V. The EVM is setup for default output currents of 538 mA per channel,
easily adjustable to different currents up to 1.65 A, for an LED stack between approximately 3 V to nearly
65 V. The TPS92518 provides high efficiency, high bandwidth, fast PWM dimming, SPI dimming, and
adjustable on-time.
1.1Typical Applications
This manual outlines the operation and implementation of the TPS92518 as a dual-channel LED current
regulator with the specifications listed in Table 1. For applications with a different input voltage range or
different output voltage range, refer to the TPS92518 data sheet (SLUSCR7). The TPS92518EVM-878
evaluation board is designed to be controlled by a TI microcontroller board, part number
LEDSPIMCUEVM-879, available separately, although it can be controlled by any SPI-capable control
system. Note that the TPS92518x supports a means to enable the part without SPI communication. By
applying a voltage above the second threshold level, 23.6 V typical, on the ENABLE pin, the state of the
LEDxEN register is bypassed. This allows a TPS92518 to be powered and operated using the default
register values (for details, refer to the TPS92518 data sheet (SLUSCR7)).

The evaluation board is set up with both channel supplies connected through R15,
so power connection can be to either J1 or J18 to power both channels from a
single supply. The board silkscreen identifies power (one pin) and ground (two pins)
connections on each connector.
J2 connects the channel 1 output to the LED load, and J3 connects the channel 2
output to a separate LED load. The leads to the LED load should be twisted and
kept short to minimize voltage drop, inductance, and EMI. The board silkscreen
identifies LED+ and LED– and GND.
J4 allows attachment of a header cable for SPI control of the chip. The board
silkscreen identifies GND, MISO, MOSI, SCK, and SSN.
J10 and J11 allow daisy-chaining TPS92518EVM-878 boards to each other with one
LEDSPIMCUEVM-879 control board attached to the left-hand side of the left-most
evaluation board for controlling the TPS92518. This interface allows control of the
chip hardware enable line, PWM inputs to both channels, SPI lines, and hardware
address lines for multiple SSN settings for systems that have multiple
TPS92518EVM-878 boards controlled by a single LEDSPIMCUEVM-879 controller
interface board.
J12 and J14 provide for two different values of pullup resistor to the MISO line, 2.2
kΩ and 4.7 kΩ provided on the evaluation board.

external source (when jumper is removed and the signal is connected to pin 1 one
of the connector). J13 provides PWM to channel 1 of the chip, while J15 provides
PWM to channel 2.
J9 allows configuration of the SSN chip select line for use with multiple chips on the
same SPI bus.
This jumper enables configurations: shorting pins 5–6 sets the SPI communication
architecture up for a single TPS92518 or the end point of a daisy chain of them,
shorting 1–2 and 5–6 sets up for a TPS92518 in the middle of a daisy-chain, and
shorting 3–4 and 5–6 provides for a star architecture.
If this jumper is closed, it allows multiple TPS92518 devices to be connected in a
star configuration.
This connector allows the TPS92518 board to attach to a microcontroller, such as
the LEDSPIMCUEVM-879.

Shunt FET dimming is simple with the TPS92518. Short leads between the evaluation board and the LED
load boards are important to prevent V
board also helps to reduce V
overshoot. Adding an appropriately rated diode from the LED+ line that

overshoot. Locating the shunt FET on or near the LED load
LED
conducts back to the positive VINinput will clamp voltage overshoot.
NOTE:There is no provision for mounting such a diode on the board: it must be soldered into the
wiring used to connect the shunt FET into the circuit.
Similarly, repopulating R17 and C21 with different values will also protect the V
pin from overshoots.
LED
Figure 12 illustrates the circuitry modifications for shunt FET dimming: increasing the size of R17, adding
a diode to VIN, and adding an appropriately-rated FET with a gate pulldown resistor. Either adding a diode
or increasing R17 should be adequate. While the modified schematic shows both output capacitors
removed, replacing one with a 220-pF capacitor rather than just removing both may give better V
overshoot performance.

3.4.4Undervoltage Lockout Description
The TPS92518 can be set up with undervoltage lockout protection with the ability to change the turn-on
threshold and hysteresis, by populating a resistive divider that is unpopulated on the evaluation board.
This involves loading R1 and changing the value of R2, and possibly populating C28. For details refer to
the TPS92518 data sheet (SLUSCR7).
Double-click on TPS92518 Demonstration Kit Installer.exe and click ‘yes’ when Windows Account Control
asks to allow the program to make changes to the computer.
This will bring up the evaluation software screen:
Quick Start: Provide input power of 6.5 V to 65 V to VIN, provide LED loads with output voltages of
between 2 V and 64 V to the two output channels. Next click on the TPS92518 Enabled box so it is
checked, then on the Buck 1 Enable: and Buck 2 Enable: boxes so they are checked. The integrated
circuit should start switching on each channel and regulating current to the LED loads.
Design Customization and GUI Operation: Access to key TPS92518 registers is provided via the GUI
main window. Each channel Peak Threshold, Off Time and Maximum Off-time can be adjusted using
the respective slider. Minimum limits are enforced in the GUI for the Off-Time and Maximum Off-time as
these values should not be set <10 except under specific and controlled conditions. (see the datasheet
section: Off-Time Thresholds - LEDx_TOFF_DAC and LEDx_MAXOFF_DAC) The registers can still be set
manually to lower values via the SPI Command section of the GUI. The sliders can be moved and the
affect on the output current and switching frequency observed.
For a specific design configuration, the Design Tool button can be selected. This opens a simple
TPS92518 design calculator window. Design Parameters can be entered and adjusted. Component and
register values will be calculated. This calculator can be used to aid in any TPS92518 design, and is not
just for use with the EVM.
For each slider adjustment an estimation of the relevant parameter value is also shown. For the peak
current estimate, the value of the sense resistor can be set in the area below the sliders. (default is the
actual EVM value of 0.15 Ohms) The estimated off-time and maximum off-times are also updated and
reflect the current LED output voltage as measured by the TPS92518x internal ADC.
In the GUI Control section, the TPS92518 enable pin voltage can be controlled via the enable check box.
The GUI also provides the ability to create PWM dimming signals. A PWM duty cycle and frequency can
be set creating the corresponding signal at the TPS92518 PWMx pin. In normal operation the PWM duty
cycle must be left at 100% to disable PWM dimming.
Registers may also be written manually via the SPI Command section. By using the TPS92518 datasheet
Registers section as a guide, specific registers can be manually read and written. To preform a register
write, set the write check-box. Un-check the box for a read. When reading and writing manually it is best
to disable the Auto Refresh of the registers by toggling the feature via the 'Auto Refresh' box. Once the
register value and write data (if applicable) are set, select the Send Command button. Due to the nature of
a SPI bus operation, read commands must be sent twice; once to load the read command and another
time to clock out the requested data.

6Use of LEDSPIMCUEVM-879 Microcontroller Board for SPI Communications with the
TPS92518
The LEDSPIMCUEVM-879 evaluation board is available separately to be used with TI's TPS92518 Bench
Evaluation Software. It comes with firmware installed that converts the software settings into SPI and
hardware-generated PWM signals to drive the TPS92518. It is set up correctly as packaged, but make
sure that jumpers J6, J7, J8, and J9 are all shorted. These provide the power for the SPI pullup hardware,
the PWM signals, and the enable signal to the TPS92518. Reprogramming the LEDSPIMCUEVM-879 is
beyond the scope of this document, and firmware for reflashing the existing board is not supplied. The
board has DC isolation between the USB section and the TPS92518 driver section, and voltage
translators to handle the I/O logic level requirements of the TPS92518. Schematics are supplied as a
guide to determining if the microcontroller board has been damaged and is not communicating correctly
with the TPS92518 evaluation board.
