LM2576HVS-5.0RG

HANSCHIP semiconductor · DC-DC Converters · TO-263-5

LM2576HVS-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 Supply input voltage pin; maximum 55 V for the LM2576HV (40 V for LM2576).
2 Output output Switching output of the regulator, which drives the external inductor and catch diode and delivers up to 3 A.
3 Ground power_in Ground pin; the package tab is also ground.
4 Feedback input Feedback sense input that regulates the output voltage; on fixed-output parts such as the 5.0 V version it connects to the output.
5 ON/OFF input Active-low shutdown input with TTL-compatible levels; VIH is 1.4 V typical and VIL is 1.2 V typical, and the pin accepts -0.3 V to +VIN.
6 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
