UCC2800DTR 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	COMP is the error amplifier output and PWM comparator input, can both source and sink current, and forcing it to GND commands zero duty cycle.
2	FB	input	FB is the inverting input of the error amplifier, and its lead length and stray capacitance should be kept as small as possible for best stability.
3	CS	input	CS is the input to the PWM and overcurrent comparators, with 100-ns leading-edge blanking after the rising edge of OUT, and exceeding the overcurrent threshold causes a soft-start cycle.
4	RC	input	RC is the oscillator timing pin, with timing resistors between 10 kΩ and 200 kΩ from REF and timing capacitors between 100 pF and 1000 pF to GND, and a timing resistor less than 10 kΩ must never be used.
5	GND	power_in	GND is the reference ground and power ground for all functions on this part.
6	OUT	output	OUT is a high-current power driver for a power MOSFET gate with peak currents exceeding ±750 mA, and it is actively held low when VCC is below the UVLO threshold.
7	VCC	power_in	VCC is the power input, which in normal operation is supplied through a current-limiting resistor and requires a minimum of 1 µF in parallel with a 0.1-µF ceramic capacitor to GND placed close to the device.
8	REF	output	REF is the voltage reference for the error amplifier and other functions, is pulled to ground through 5 kΩ when VCC is above 1 V and below UVLO, and requires a minimum of 0.1-µF ceramic bypass to GND.
