LM2575HVS-5.0 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 input supply, rated up to 60 V for the LM2575HV (40 V for the LM2575); abs max VIN 60 V. |
| 2 | Output | output | Switching output of the internal power transistor; output voltage to ground (steady state) is -1 V, with 2 A guaranteed output current. |
| 3 | Ground | power_in | Ground pin; the package tab is also connected to GND. |
| 4 | Feedback | input | Feedback sense input; on the 5.0 V fixed version it connects to the output (internal divider), with the adjustable version reference at 1.23 V. |
| 5 | ON/OFF | input | Active-low TTL shutdown input: VIH 2.2 V min/VIL 1.0 V max, input range -0.3 V to +VIN, standby current about 50 µA typical when high. |
| 6 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
