NCP3065D2SLDGEVB:SEPIC LED DRV 350MA
This circuit is intended for driving high power LEDs. It is designed for such wide input nominal 12 Vdc applications as automotive and low voltage lighting (12 Vdc/12 Vac). An optional dimming PWM input is included. The circuit is based on NCP3065 operation at 250 kHz 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.
