MP3336A

Dual-Channel, Flash LED Driver with 2A/Ch and I²C Interface

Datasheet

概要

The MP3336A is a compact, dual-channel, high-power, flash LED driver that can drive up to 2A in flash mode for each LED. The MP3336A improves image and video quality in low light environments for camera phones. 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 highly efficient, optimized solution for smaller PCB spaces.

The MP3336A features a standard I²C interface, dual LED channels, rich protection modes, and high power density and performance. The MP3336A can also support flash, assist, indicator, and 5V DC modes.

The cathodes of the dual-flash LED are referenced to GND, which improves thermal performance in layout. The MP3336A is available in a WLCSP-20 (1.6mmx2.0mm) package.
