LM2575HVR-5.0

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

LM2575HVR-5.0 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 with an operating supply voltage up to 60 V and an absolute maximum of 63 V.
2 VOUT power_out Regulated output pin; the steady-state output voltage to ground is rated down to -0.75 V.
3 GND power_in Ground reference pin that must be connected with short, single-point or ground-plane return paths for best regulation.
4 FB/ADJ input Feedback pin that senses the output; for the adjustable version, VOUT = VREF(1+R2/R1) with VREF = 1.23 V.
5 ON/OFF input TTL-compatible shutdown input that switches the regulator off when driven high, giving a typical standby current of 50 uA.
6 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
