LM2575HVS-ADJ

UMW · DC-DC Converters · TO-263-5

LM2575HVS-ADJ from UMW, 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. Operating range up to 60V for the HV version; absolute maximum 63V. Bypass locally with a low-ESR input capacitor.
2 Output output Switching output from the internal power transistor. Drives the external freewheeling (catch) diode and inductor of the buck stage. Rated for 2A load current.
3 GND power_in Ground reference for the regulator. Also serves as the thermal path through the exposed tab of the TO-263 package.
4 Feedback input Output voltage feedback input for the adjustable version. Internal reference VFB = 1.23V typ (1.180-1.280V limits). Connect to the midpoint of the external R1/R2 output divider; feedback bias current is 10 nA typ (100 nA max).
5 ON/OFF input TTL-compatible active-low shutdown input. Logic low or floating enables the regulator (VIL <= 1.2V typ); logic high disables it (VIH >= 1.4V typ), dropping the device to ~50 uA standby current. Do not exceed VIN; input current 12 uA typ at 2.5V.
