NCP5007EVB: NCP5007 Compact White LED Driver Evaluation Board

The NCP5007 is a high efficiency boost converter operating in a current control architecture intended to drive strings of up to 5 White LEDs for Color LCD backlighting applications. The chip has been optimized for small ceramic capacitors and is capable of supplying up to 1.0 W output power. The evaluation board can be configured to drive between 2 to 5 LEDs. The nominal LED current for this evaluation board has been set at 20mA. This can be adjusted by changing a resistor. In addition a PWM signal can be applied to the board to evaluate the dimming function.
