DESCRIPTION
The UCC3813-0/-1/-2/-3/-4/-5 family of high-speed, low-power inte
grated circuits contain all of the control and drive components required
for off-line and DC-to-DC fixed frequency current-mode switching power
supplies with minimal parts count.
These devices have the same pin configuration as the UC3842/3/4/5
family, and also offer the added features of internal full-cycle soft start
and internal leading-edge blanking of the current-sense input.
The UCC3813-0/-1/-2/-3/-4/-5 family offers a variety of package options,
temperature range options, choice of maximum duty cycle, and choice
of critical voltage levels. Lower reference parts such as the UCC3813-3
and UCC3813-5 fit best into battery operated systems, while the higher
reference and the higher UVLO hysteresis of the UCC3813-2 and
UCC3813-4 make these ideal choices for use in off-line power supplies.
The UCC2813-x series is specified for operation from –40°C to +85°C
and the UCC3813-x series is specified for operation from 0°C to +70°C.

PIN DESCRIPTIONS
COMP: COMP is the output of the error amplifier and the
input of the PWM comparator.
Unlike other devices, the error amplifier in the UCC3813
family is a true, low output-impedance, 2MHz operational
amplifier. As such, the COMP terminal can both source
and sink current. However, the error amplifier is internally
current limited, so that you can command zero duty cycle
by externally forcing COMP to GND.
The UCC3813 family features built-in full cycle Soft Start.
Soft Start is implemented as a clamp on the maximum
COMP voltage.
FB: FB is the inverting input of the error amplifier. For
best stability, keep FB lead length as short as possible
and FB stray capacitance as small as possible.
CS: CS is the input to the current sense comparators.
The UCC3813 family has two different current sense
comparators: the PWM comparator and an over-current
comparator.
The UCC3813 family contains digital current sense filter
ing, which disconnects the CS terminal from the current
sense comparator during the 100ns interval immediately
following the rising edge of the OUT pin. This digital filter
ing, also called leading-edge blanking, means that in
most applications, no analog filtering (RC filter) is re
quired on CS. Compared to an external RC filter tech
nique, the leading-edge blanking provides a smaller
effective CS to OUT propagation delay. Note, however,
that the minimum non-zero On-Time of the OUT signal is
directly affected by the leading-edge-blanking and the
CS to OUT propagation delay.
The over-current comparator is only intended for fault
sensing, and exceeding the over-current threshold will
cause a soft start cycle.
RC: RC is the oscillator timing pin. For fixed frequency
operation, set timing capacitor charging current by con
necting a resistor from REF to RC. Set frequency by con
necting a timing capacitor from RC to GND. For best
performance, keep the timing capacitor lead to GND as
short and direct as possible. If possible, use separate
ground traces for the timing capacitor and all other func
tions.

PIN DESCRIPTIONS (cont.)
The frequency of oscillation can be estimated with the
following equations:
UCCx813-0/-1/-2/-4:
UCCx813-3, UCCx813-5:
where frequency is in Hz, resistance is in W, and capaci
tance is in farads. The recommended range of timing re
sistors is between 10k and 200k and timing capacitor is
100pF to 1000pF. Never use a timing resistor less than
10k.
GND: GND is reference ground and power ground for all
functions on this part.
OUT:OUT is the output of a high-current power driver ca
pable of driving the gate of a power MOSFET with peak
currents exceeding ±750mA. OUT is actively held low
when VCC is below the UVLO threshold.
The high-current power driver consists of FET output devices, which can switch all of the way to GND and all of
the way to VCC. The output stage also provides a very
low impedance to overshoot and undershoot. This
means that in many cases, external schottky clamp diodes are not required.
VCC: VCC is the power input connection for this device.
In normal operation VCC is powered through a current
limiting resistor. Although quiescent VCC current is very

low, total supply current will be higher, depending on
OUT current. Total VCC current is the sum of quiescent
VCC current and the average OUT current. Knowing the
operating frequency and the MOSFET gate charge (Qg),
average OUT current can be calculated from:
=·
IQF
OUT g
To prevent noise problems, bypass VCC to GND with a
-
0.1 mF ceramic capacitor in parallel as close to the VCC
-
pin as possible. An electrolytic capacitor may also be
used in addition to the ceramic capacitor.
REF: REF is the voltage reference for the error amplifier
and also for many other functions on the IC. REF is also
used as the logic power supply for high speed switching
logic on the IC.
-
When VCC is greater than 1V and less than the UVLO
threshold, REF is pulled to ground through a 5kW resis
tor. This means that REF can be used as a logic output
indicating power system status. It is important for reference stability that REF is bypassed to GND with a ceramic capacitor as close to the pin as possible. An
electrolytic capacitor may also be used in addition to the
ceramic capacitor. A minimum of 0.1mF ceramic is required. Additional REF bypassing is required for external
loads greater than 2.5mA on the reference.
To prevent noise problems with high speed switching
transients, bypass REF to ground with a ceramic capacitor very close to the IC package.

APPLICATION INFORMATION
UDG-96139
The UCC3813-0/-1/-2/-3/-4/-5 oscillator generates a sawtooth waveform on RC. The rise time is set by the time constant of R
and CT. The fall time is set by CT and an internal transistor on-resistance of approximately 125W. During the fall time, the out
put is off and the maximum duty cycle is reduced below 50% or 100% depending on the part number. Larger timing capacitors
increase the discharge time and reduce the maximum duty cycle and frequency.

TBD: The Pb-Free/Green conversion plan has not been defined.
Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements
for all 6 substances, including the requirement that lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered
at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes.
Pb-Free (RoHS Exempt): This component has a RoHS exemption for either 1) lead-based flip-chip solder bumps used between the die and
package, or 2) lead-based die adhesive used between the die and leadframe. The component is otherwise considered Pb-Free (RoHS
compatible) as defined above.
Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame
retardants (Br or Sb do not exceed 0.1% by weight in homogeneous material)

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.
