TPS61040M5

HGSEMI · DC-DC Converters · SOT-23-5

TPS61040M5 from HGSEMI, 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 input Switch pin connected to the drain of the internal power MOSFET, where the inductor and Schottky diode connect, with a maximum switch voltage of 30 V.
2 GND power_in Ground pin for the device.
3 FB input Feedback pin that connects to the external voltage divider to program the output voltage, referenced to a typical 1.233 V.
4 EN input Enable pin: pulling it to ground forces shutdown with supply current below 1 mA, it must not be left floating, and the EN high threshold is 1.3 V minimum while the low threshold is 0.4 V maximum.
5 VIN power_in Supply voltage pin with an input voltage range of 1.8 V to 6 V.
