UCC3813PWTR-5

Texas Instruments · AC-DC Controllers And Regulators · TSSOP-8

UCC3813PWTR-5 from Texas Instruments, in a TSSOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 COMP output Error amplifier output and PWM comparator input with internal soft start ramping from 0.5V to REF−1V over 4ms.
2 FB input Inverting input to error amplifier; minimize trace length and parasitic capacitance for optimal stability with 2MHz gain-bandwidth.
3 CS input Current sense comparator input with 100ns leading edge blanking, 1.65V/V typical gain, and 0.9V to 1.1V input range at VCOMP = 5V.
4 RC input Oscillator timing input where external RT (10kΩ to 200kΩ recommended) and CT (100pF to 1000pF recommended) set switching frequency up to 1MHz and maximum 50% duty cycle.
5 GND power_in Signal reference ground and power ground for all device functions.
6 OUT output High current gate driver output with ±1A peak capability, actively held low below UVLO threshold, and 41-75ns rise/fall time at 1nF capacitive load.
7 VCC power_in Power supply input with UVLO turn-on at 4.1V typical and turn-off at 3.6V typical; internal zener clamp at 13.5V typical (12V to 15V range).
8 REF output 4V reference voltage (±1.5% accuracy at 25°C, 3.94V to 4.06V) biasing error amplifier and logic functions; short circuit current −5 to −35mA.
