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). |
