LM2575HVS-12RG
HANSCHIP semiconductor · DC-DC Converters · TO-263-5
LM2575HVS-12RG 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 | Supply input; maximum VIN is 55 V for the LM2575HV versions (40 V for LM2575), recommended operating range up to 55 V for HV. |
| 2 | Output | output | Switching output of the internal power transistor; output saturation voltage is 1.4 V typical at 2 A, and the pin is rated to -1 V steady state. |
| 3 | Ground | power_in | Ground pin; the package tab is also connected to GND. |
| 4 | Feedback | input | Feedback input sensing the output voltage to regulate the 12 V fixed output (1.23 V reference on the adjustable version). |
| 5 | ON/OFF | input | Active-low shutdown input, TTL compatible; input range -0.3 V to VIN, and standby current is 50 µA typical when held high (off). |
| 6 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
