TPS61041DBVRG

HANSCHIP semiconductor · LED Drivers · SOT-23-5

TPS61041DBVRG from HANSCHIP semiconductor, in a SOT-23-5. 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 SW output Switch node connected to the drain of the internal power MOSFET, where the inductor and Schottky diode connect; the datasheet lists the maximum switch voltage as 30 V.
2 GND power_in Ground reference pin for the device.
3 FB input Feedback pin that connects to the external voltage divider to set the output voltage, with VOUT = 1.233 V × (1 + R1/R2) and EN and FB rated to VIN + 0.3 V maximum.
4 EN input Enable pin; pulling it to ground forces shutdown with supply current below 1 µA, and it must not be left floating and needs to be terminated.
5 VIN power_in Supply voltage pin with an input voltage range of 1.8 V to 6 V.
