SY5072BABT

Silergy Corp · AC-DC Controllers And Regulators · SOT-23-6

SY5072BABT from Silergy Corp, 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 ISEN input Current limit and zero-crossing sense pin; the current limit threshold is 0.44 to 0.55 V (0.50 V typ) and the pin tolerates -0.3 V to 25 V, with a dynamic negative current of -2 mA for 50 µs.
2 GND power_in Ground pin for the controller.
3 COMP passive Loop compensation pin; connect an RC network across this pin and ground to stabilize the control loop, with an absolute maximum rating of 3.6 V.
4 FB input Feedback pin that receives the output voltage divider signal, referenced to an internal 1.25 V reference (1.232 to 1.268 V), with an absolute maximum rating of 3.6 V.
5 VIN power_in Power supply pin with a recommended operating range of 9 V to 22 V, an absolute maximum rating of -0.3 V to 28 V, and an OVP threshold of 22 to 26 V.
6 DRV output Gate driver output that connects to the MOSFET gate through a resistor, with an absolute maximum rating of -0.3 V to 25 V and typical source/sink currents of 70 mA / 400 mA.
