DESCRIPTION
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.
