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 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.
