The MP3336A is a compact, dual-channel, highpower, 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 MP3336A 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 MP3336A provides a high efficiency and optimized solution for smaller PCB spaces.
The MP3336A features a standard I2C interface, dual LED channels, rich protection modes, and high power density and performances. The MP3336A can also support flash, assist, 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 MP3336A is available in a WLCSP-20 (1.6mmx2.0mm) package.
