NCP3066, NCV3066

Up to 1.5 A Constant

Current Switching

Regulator for LEDs with

ON/OFF Function

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.
