产品信息

The NCP3066 is a monolithic Buck Boost Inverting 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 12 Vac or 12 Vdc supply, commonly used for lighting applications as well as unregulated supplies such as rechargeable batteries. The NCP3066 switching regulator can be configured in Step-Down (Buck) and Step-Up (Boost) and Voltage-Inverting topologies with a minimum number of external components. An NCV3066 automotive version is available and without the ON/OFF feature as the NCP3065.
