NCP3066DFSEPGEVB:NCP3066 DFN SEPIC DB
The NCP3066 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 NCP3066 has a wide input voltage up to 40 V to allow it to operate from 12 Vac or 12 Vdc supply, commonly used for lighting applications as well as unregulated supplies such as rechargeable batteries. The ON/OFF function allows turn the device to low consumption mode or regulate the brightness of LEDs. A SEPIC (single-ended primary inductance converter) is distinguished by the fact that its input voltage range can overlap the output voltage at LEDs string. Size: 77mm x 37mm x 15mm, silk-screen diameter: 30 mm
