HG1501S-5.0 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 suppress supply noise. |
| 2 | OUTPUT | output | Power switch output and switching node that supplies the output load. |
| 3 | GND | power_in | Ground pin, which in layout should sit on the output capacitor ground path outside the Schottky diode loop to keep switching current spikes from adding noise. |
| 4 | FEEDBACK | input | Voltage feedback pin that monitors the output through an external resistor divider, 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, defaulting to low when floating (threshold high 1.4V, low 0.8V). |
| 6 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
