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

the addition of an external transistor to support higher LED currents

beyond the 1.5ꢀA rated switch current of the internal transistor. The

NCP3065 switching regulator can be configured in Step-Down

(Buck) and Step-Up (boost) topologies with a minimum number of

external components.
