Product Summary

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 1.5A 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.
