NCP3065DR2G Datasheet PDF - ON Semiconductor

●The NCP3065DR2G is a constant current monolithic Switching Regulator designed to deliver constant current for powering high brightness LEDs. The device has a very low feedback voltage of 235mV (nominal) which is used to regulate the average current of the LED string. 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 switching regulator can be configured in step-down (buck) and step-up (boost) topologies with a minimum number of external components.

● Cycle-by-cycle current limit

● No control loop compensation required

● Operation with all ceramic output capacitors or no output capacitance

● Analogue and digital PWM dimming capability

● Internal thermal shutdown with hysteresis
