NCP3065, NCV3065
Up to 1.5 A Constant Current
Switching Regulator for LEDs
The NCP3065 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
NCP3065 has a wide input voltage up to 40 V to allow it to operate
from 12 Vac or 12 Vdc supplies commonly used for lighting
applications as well as unregulated supplies such as Lead Acid
batteries. The device can be configured in a controller topology with
