LM2575HVR-12

HTC Korea TAEJIN Tech · DC-DC Converters · TO-263-5L

LM2575HVR-12 from HTC Korea TAEJIN Tech, in a TO-263-5L. 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 Input supply pin; the operating supply voltage is limited to 60 V, with an absolute maximum input supply voltage of 63 V.
2 VOUT power_out Regulated output pin that supplies the 1 A guaranteed output current, with an absolute maximum output voltage to ground of -0.75 V in steady state.
3 GND power_in Ground reference pin; single-point grounding or a ground plane should be used for best results, with the leads kept short.
4 FB/ADJ input Output voltage feedback input on the fixed-output versions and output adjust input on the adjustable version, where the internal reference is VREF = 1.23 V.
5 ON/OFF input TTL-compatible shutdown input where a 5 V level (OFF) puts the device in low-power standby with about 50 µA typical standby current, and the pin must stay between -0.3 V and VIN.
6 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
