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).
