LM2595S-5.0RG
HANSCHIP semiconductor · DC-DC Converters · TO-263-5L
LM2595S-5.0RG from HANSCHIP semiconductor, in a TO-263-5L. 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 | OUTPUT | output | Power switch output pin that forms the switching node and supplies the output load. |
| 2 | VIN | power_in | Supply input that requires a DC source of 4.5 V to 40 V, with a large-value capacitor placed between VIN and GND to filter supply noise. |
| 3 | GND | power_in | Ground pin that should be laid out so its return path avoids the Schottky diode output point, limiting switching-current spike noise. |
| 4 | FEEDBACK | input | Voltage feedback pin that senses the output through an external resistor divider and regulates to a 1.23 V threshold. |
| 5 | ON_OFF | input | Enable pin in which a low level turns the chip on and a high level turns it off, and a floating pin defaults to low; the datasheet gives an off threshold of 1.4 V and an on threshold of 0.8 V. |
| 6 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
