DESCRIPTION

The MP3336 is a compact, dual-channel, high-

power, flash, LED driver that 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 environments. The MP3336

operates with a selectable 1/2/3/4MHz switching

frequency and uses a synchronous, current-mode

PWM boost converter to regulate the LED current

with two high-current sources. The MP3336

provides high efficiency and an optimized solution

for smaller PCB spaces.

dual LED channels, rich protection modes, and

high power density and performances. The

MP3336 can also support flash, assist, torch,

indicator, and 5V DC modes.

The cathodes of the dual-flash LED are

referenced to GND, which is better for improving

thermal performance in layout. The MP3336 is

available in a WLCSP-20 (1.6mmx2.0mm)

package.
