NCP3065D1SLDGEVB

The NCP3065D1SLDGEVB is a SEPIC LED driver evaluation board which is designed to display the full functionality and flexibility of NCP3065 which is a monolithic buck/boost/inverting switching regulator. The NCP3065 is designed to deliver constant current for powering high brightness LEDs. This IC has a very low feedback voltage of 235mV (nominal) which is used to regulate the average current of the LED string. In addition, the NCP3065 has a wide input voltage up to 40V to allow it to operate from 12Vac or 12Vdc supplies. The NCP3065 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), step up (boost) or SEPIC topologies with a minimum number of external components.
