AP1501S-5.0RG

HANSCHIP semiconductor · DC-DC Converters · TO-263-5

AP1501S-5.0RG from HANSCHIP semiconductor, 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 that requires a DC source of 4.5V to 40V, with a large-value capacitor placed between this pin and GND to suppress supply noise.
2 OUTPUT output Power switch output pin that is a switching node driving the output load.
3 GND power_in Ground pin that should be routed so the output capacitor ground path stays separate from the Schottky diode, preventing switching-current spikes from coupling noise into the circuit.
4 FEEDBACK input Voltage feedback pin that senses the output through an external resistor divider, with a 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 (VIH 1.4V, VIL 0.8V), and it defaults to low when floating.
6 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
