UCC28722DBVR

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

UCC28722DBVR from Texas Instruments, in a SOT-23-6. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 CBC input Cable compensation programming pin. A resistor from CBC to GND (recommended max 10 kΩ) programs compensation for the voltage drop in the output cable.
2 VDD power_in Bias supply input to the controller. Operating range 9 V to 35 V (38 V absolute max); requires a 1-10 µF bypass capacitor to GND placed close to the pin.
3 DRV output Drive output to the base of an external high-voltage NPN BJT power switch. Continuous base current sink capability up to 50 mA; source current is self-limiting.
4 CS input Current-sense input connected to a ground-referenced current-sense resistor in series with the power switch, used to monitor and control peak primary current. A series resistor may be added to compensate peak switch current versus AC-mains input variation. Absolute max −0.5 V to 5 V.
5 GND power_in Ground reference for the controller and low-side return for the DRV output. Return all AC decoupling capacitors as close as possible to this pin and avoid common trace length with analog signal returns.
6 VS input Voltage-sense input for voltage and timing feedback, connected to a resistor divider from an auxiliary flyback winding to GND. The upper divider resistor value programs the AC-mains run/stop thresholds and line compensation at the CS pin. Absolute max −0.75 V to 7 V; peak current −1.2 mA.
