NCV3066DR2G Datasheet PDF - ON Semiconductor

●Up to 1.5 A Constant Current Switching Regulator for LEDs with ON/OFF Function

●The NCP3066 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 NCP3066 has a wide input voltage up to 40 V to allow it to operate from a 12 Vac or a 12−36 Vdc supply, commonly used for lighting applications as well as unregulated supplies such as rechargeable batteries.
