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 1236 Vdc supply, commonly used for lighting applications as well as unregulated supplies such as rechargeable batteries. The NCP3066 Switching Regulator CAN be configured in StepDown (Buck), StepUp (Boost) and VoltageInverting topologies with a minimum number of external components. The ON/OFF pin provides PWM dimming capability or a low power shutdown mode. By ON Semiconductor
