DESCRIPTION

The MP3336 is a dual-channel and high-power

flash LED driver with very compact package. It

can drive up to 2A in flash mode for each LED.

It is usually applied for camera phones to

improve image and video quality in low light

environment.

The

device

operates

in1/2/3/4MHz synchronous, current-mode PWM

boost converter to regulate the LED current with

two high current source. The MP3336 provides

an optimized solution for smaller PCB space

and higher efficiency.

dual LED channels, rich protection modes and

high power density and performances. It

supports

flash/assist/torch/indicator/5V

DC

modes.

The cathodes of the dual flash LED are

referenced to GND, which is better for layout to

improve thermal performance. It is available in

WLCSP20-1.6X2.0mm package.
