NCP3065D3SLDGEVB

The NCP3065D3SLDGEVB is an evaluation board to evaluate NCP3065 monolithic buck/boost/inverting switching regulator. The NCP3065 is designed to deliver constant current for powering high brightness LEDs. This IC can be configured in step down (buck), step up (boost) or SEPIC topologies with a minimum number of external components. The NCP3065D3SLDGEVB is a SEPIC 700mA LED driver evaluation board and its intended for driving high power LEDs and it is designed for such wide input nominal 12Vdc applications as automotive and low voltage lighting (12Vdc/12Vac). The NCP3065D3SLDGEVB is based on NCP3065 operation at 250KHz in a non isolated configuration. The primary advantages of this circuit are in the wide input voltage range, wide output voltage range, and in its high efficiency. A pulse feedback resistor (R8) is used to vary the slope of the oscillator ramp, achieving duty cycle control and steady switching frequency over a wide input voltage range.
