Upgrade to myMPS+Product 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.

IC Details
The MP3214 is a low noise, high current charge pump designed to 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 controls the inrush current via a soft start algorithm. High frequency switching of the charge pump capacitors allows for very small capacitance values. The output current is set by an external resistor, RSET. The brightness of the LED can be modulated by a PWM on the enable pin. The MP3214 automatically adjusts the switching mode of the charge pump for optimal efficiency. The MP3214 is available in a 16 pin 3x3 QFN package.
