LM2575HVS-15

HGSEMI · DC-DC Converters · TO-263-5

LM2575HVS-15 from HGSEMI, 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; maximum 60 V for the LM2575HV versions (recommended VIN 60 V max).
2 Output output Switch output of the internal power transistor, with 2 A rated output current and saturation voltage of 1.4 V typical at 2 A.
3 Ground power_in Ground pin of the regulator.
4 Feedback input Feedback sense input connected to the output voltage; for the fixed 15 V version it senses VOUT through the internal divider.
5 ON/OFF input Active-low shutdown input; logic high (VIH 1.4 V typ, max VIN) turns the regulator off to a standby current of 50 µA typical, and low (VIL 1.2 V typ) enables it.
6 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
