DATA SHEET www.onsemi.com Constant Current Step-Up/ Step-Down/Inverting Switching Regulator for HB-LEDs 1.5 A NCP3065, NCV3065 The NCP3065 is a monolithic switching regulator designed to deliver constant current for powering high brightness LEDs.

The device has a very low feedback voltage of 235 mV (nominal) which is used to regulate the average current of the LED string.

In addition, the NCP3065 has a wide input voltage up to 40 V to allow it to operate from 12 Vac or 12 Vdc supplies commonly
