LM2576HVR-ADJ

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

LM2576HVR-ADJ from HTC Korea TAEJIN Tech, in a TO-263-5. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 VIN power_in Input supply voltage. Accepts unregulated DC input up to 60V (63V absolute max). Bypass with a 100uF/75V aluminum electrolytic capacitor close to this pin.
2 VOUT output Switching output pin from the internal power transistor. Drives the external catch diode and inductor (typ. 100uH); sources up to 3A load current with ~1.4V saturation.
3 GND power_in Ground return for the regulator. Use single-point grounding or ground plane to minimize switching noise.
4 FB/ADJ input Feedback / output adjust pin. Internal reference is 1.23V; set VOUT = VREF x (1 + R2/R1) with R1 between 1kΩ and 5kΩ. Feedback bias current is typically 50nA.
5 ON/OFF input TTL-compatible shutdown input. Logic low (<0.8V typ) enables the regulator; logic high (>2.4V) disables it, entering low-power standby (~50uA at VIN=60V). Do not leave floating.
