LM2576HVS-3.3RG

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

LM2576HVS-3.3RG 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 Unregulated supply input, with a maximum of 55V for the LM2576HV series (40V for LM2576).
2 Output output Switching output of the internal power transistor, which delivers up to 3A to the load, with the output voltage limited to -1V below ground in steady state.
3 Ground power_in Ground pin of the regulator, and the package tab is also connected to ground.
4 Feedback input Feedback sense input that regulates the fixed 3.3V output of the LM2576HV-3.3.
5 ON/OFF input Active-low TTL-compatible shutdown input, with an input range of -0.3V to +VIN, a logic-high threshold of 1.4V typical and a 50µA typical standby current when off.
6 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
