Constant Current Step-Up/ Step-Down/Inverting Switching
Regulator for HB-LEDs with Enable
1.
5 A
NCP3066, NCV3066
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.
The NCP3066 switching
regulator can be configured in Step−Down (Buck), Step−Up (Boost) ...
