UCC2807DTR-3

Texas Instruments · DC-DC Converters · SOIC-8

UCC2807DTR-3 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 TRIG input Oscillator timing input with an RC-type charge/discharge signal controlling the internal oscillator; signal minimum 1/3 VDD, maximum 2/3 VDD.
2 COMP output Output of the error amplifier and input of the PWM comparator; can source and sink current, and forcing it to GND gives zero duty cycle.
3 FB input Inverting input to the error amplifier; keep connections short and stray capacitance small for best stability.
4 CS input Current sense input to the PWM and overcurrent comparators, with 100ns leading edge blanking after the rising edge at OUT; absolute maximum -0.3V to VDD+0.3V.
5 GND power_in Reference ground and power ground for all functions of the part.
6 OUT output High current totem pole power driver output for a power MOSFET gate, with peak currents exceeding 1A (absolute maximum ±1A), actively held low when VDD is below the UVLO threshold.
7 VDD power_in Power input connection; absolute maximum supply voltage 13.5V (IDD ≤10mA), UCCx807-3 start threshold 4.3V typ and turn-off 4.1V typ, bypass to GND with a ceramic capacitor close to the chip.
8 DISCH passive Provides the low impedance discharge path for the external RC timing network during normal oscillator operation.
