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.
The MP3336 features a standard I2C interface, 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.
