The EV3214DQ-00A is an evaluation board for the MP3214, a low noise, high current LED driver intended for camera phone application. It can drive LEDs at up to 500mA with an input supply of 2.7 to 5.5 volts.
The high efficiency and low external parts count (two small bypass caps, two small charge pump caps and one programming resistor) make the MP3214 ideally suited for portable applications where small size and high efficiency are critical.
The MP3214 employs an efficient inductor less charge pump with 1x, 1.5x and 2x automatic mode control to achieve high efficiency power conversions.
