LM2575HVS-5.0RG

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

LM2575HVS-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 Unregulated supply input, rated up to 55V for the LM2575HV (40V for LM2575) per the absolute maximum ratings.
2 Output output Switching regulator output of the internal 2A power switch, with cycle-by-cycle current limit and thermal shutdown protection.
3 Ground power_in Ground pin; the package tab is also ground.
4 Feedback input Feedback sense input for regulating the output voltage; for the fixed 5.0V version it connects to the output.
5 ON/OFF input Active-low shutdown input with TTL capability, voltage range -0.3V to VIN, giving about 50uA typical standby current when high.
6 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
