LM2596HVS-12RG
HANSCHIP semiconductor · DC-DC Converters · TO-263-5
LM2596HVS-12RG 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 4.5V to 40V (57V for HV types), with a large capacitor between the supply pin and ground to suppress supply noise. |
| 2 | OUTPUT | power_out | Power switch output pin that acts as the switching node supplying the output load. |
| 3 | GND | power_in | Ground pin that should be routed on the layout along the output ground path away from the Schottky diode to limit switching-current spike noise. |
| 4 | FEEDBACK | input | Voltage feedback pin that monitors the output through a resistor divider network, with a feedback threshold voltage of 1.23V. |
| 5 | ON_OFF | input | Enable pin where a high level (switch-pin threshold 1.4V for OFF) turns the chip off and a low level (0.8V for ON) turns it on; it defaults to low when floating. |
| 6 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
