UCC2813PWTR-1

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

UCC2813PWTR-1 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; feedback loop compensation applied between COMP and FB pins; supports 0.4 to 2.5 mA drain current and -0.2 to -0.8 mA source current; internal soft-start ramps voltage from 0V to REF-1V over 4ms.
2 FB input Inverting input of error amplifier with -2 to 2 µA input bias current; minimize lead length and stray capacitance for best stability.
3 CS input Current sensing comparator input with 100ns internal leading-edge blanking; gain 1.1 to 1.8 V/V with 1.65 V/V typical; maximum input signal 0.9 to 1.1V; overcurrent threshold 1.32 to 1.7V; input bias current ±200 nA.
4 RC input Oscillator timing pin for programming switching frequency and maximum duty cycle using external RC network; recommended timing resistor 10kΩ to 200kΩ and timing capacitor 100pF to 1000pF; keep leads short and directly connected to GND.
5 GND power_in Signal reference ground and power ground for all device functions; use separate ground trace for timing capacitor and critical signal paths.
6 OUT output High-current power driver output capable of ±750mA to ±1A peak current for MOSFET gate drive; output low 0.1-0.4V at 20mA, output high VVCC-0.15-0.4V at -20mA; rise time 41-70ns, fall time 44-75ns with 1nF load; actively held low when VCC below UVLO threshold.
7 VCC power_in Power supply bias input; minimum 11V for normal operation; startup current 0.1-0.23 mA, operating current 0.5-1.2 mA; internal Zener clamp at 12-13.5V nominal; bypass to GND with 0.1µF ceramic capacitor placed close to pin.
8 REF power_out Voltage reference output 5V nominal with ±1.5% tolerance; bias source for error amplifier and IC logic functions; load regulation 10-30mV for 0.2-5mA load current; output noise 70µV (10Hz-10kHz); maximum 5mA output current; bypass to GND with minimum 0.1µF ceramic capacitor.
