HG1501S-3.3

HGSEMI · DC-DC Converters · TO-263-5

HG1501S-3.3 from HGSEMI, in a TO-263-5. 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 VIN power_in Supply input requiring a 4.5V~40V DC source (60V for HV types), with a large capacitor placed between this pin and ground to remove supply noise.
2 OUTPUT output Power switch output pin, a switching node that supplies the output load.
3 GND power_in Ground pin, which should be placed on the output capacitor ground path outside the Schottky diode to prevent switching current spikes from adding noise.
4 FEEDBACK input Voltage feedback pin that monitors the output voltage through an external resistor divider for regulation, with a feedback threshold voltage of 1.23V.
5 ON_OFF input Enable pin where a low level turns the chip on and a high level turns it off (high above 1.4V, low below 0.8V), defaulting to low when floating.
6 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
