LM2596HVS-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 | Input supply pin that requires a DC supply of 4.5 V to 40 V (57 V for the HV version); a large capacitor should be placed between this pin and ground to suppress supply noise. |
| 2 | OUTPUT | output | Power switch output pin, a switching node that delivers power to the output load through the internal power transistor. |
| 3 | GND | power_in | Ground pin that should be routed on a ground path separate from the Schottky diode output point to keep switching-current spikes from coupling noise into the supply. |
| 4 | FEEDBACK | bidirectional | Voltage feedback pin that senses the output through an external resistor divider and regulates it, with a feedback threshold of 1.23 V. |
| 5 | ON_OFF | input | Enable pin in which a high level (above 1.4 V per the electrical table) turns the chip off and a low level (below 0.8 V) turns it on; the pin defaults to low when floating. |
| 6 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
