Features & Applications
The NCP3066 are monolithic switching regulators 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.
The NCP3066 switching regulator can be configured in Step−Down (Buck), Step−Up (Boost) and Voltage−Inverting topologies with a minimum number of external components. The ON/OFF pin provides PWM dimming capability or a low power shutdown mode.
