UCC3813D-0

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

UCC3813D-0 from Texas Instruments, in a SOIC-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; receives feedback compensation and provides ramp voltage for PWM control logic.
2 FB input Inverting input of the error amplifier for output voltage feedback control and regulation.
3 CS input Current sense input to PWM and overcurrent comparators; includes internal 100ns leading edge blanking to reject switching transients.
4 RC input Oscillator timing pin with external R-C network for programming switching frequency up to 1MHz and maximum duty cycle 100%.
5 GND power_in Signal reference ground and power ground for all device functions and internal circuits.
6 OUT output High-current gate driver output capable of ±1A peak current for power MOSFET control; actively held low during UVLO condition.
7 VCC power_in Bias power supply input with internal regulation to 13.5V; absolute maximum rating 12V requires series limiting resistor from higher voltage sources.
8 REF power_out Precision 5V voltage reference output (1.5% accuracy at 25°C) providing bias and reference for error amplifier and internal logic circuits; 5mA maximum output current rating.
