UCC28700DBVR

Texas Instruments · AC-DC Controllers And Regulators · SOT-23-6

UCC28700DBVR from Texas Instruments, in a SOT-23-6. 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 CBC input Cable compensation input pin programmed through resistor to GND for maximum 400 mV voltage compensation at 5-V output.
2 VDD power_in Bias supply input with 9 to 35 V operating range, 21 V UVLO turn-on threshold, 8.1 V turn-off threshold, requires bypass capacitor to GND.
3 DRV output Gate-drive output with 14-V clamp for external MOSFET switching transistor gate, providing 25-mA turn-on current source.
4 CS input Current-sense input with 0.75-V IPP(max) and 0.25-V IPP(min) thresholds, featuring 235-ns leading-edge blanking time.
5 GND power_in Ground reference pin for the controller and low-side return for gate-drive output.
6 VS power_in Voltage-sense input from auxiliary winding voltage divider providing output voltage feedback information sampled at demagnetization time.
