LM2596HVS-ADJRG 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 pin requiring a DC supply of 4.5 V to 40 V, or 57 V for the HV version, with a large-value capacitor between this pin and ground recommended to suppress supply noise. |
| 2 | OUTPUT | output | Power switch output pin that forms the switching node supplying the output load. |
| 3 | GND | power_in | Ground pin that should be routed on a ground return path that avoids the Schottky diode output point, to keep switching current spikes from coupling noise into the supply. |
| 4 | FEEDBACK | input | Voltage feedback pin that senses the output through an external resistor divider, with a feedback threshold of 1.23 V. |
| 5 | ON_OFF | input | Enable/shutdown pin where a high level turns the chip off and a low level enables it, with the pin defaulting to low when floating; the electrical table gives thresholds of 1.4 V (off) and 0.8 V (on). |
| 6 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
