Product Description

The MP3332 is a dual-channel, flash LED driver for high-resolution camera phones. It comes in a very compact package and is highly efficient at improving image and video quality in low-light environments. The synchronous boost converter operates at 1/2/3/4MHz to provide higher efficiency and an optimized solution for smaller PCB spaces. The MP3332 features a standard I2C interface, dual LED channels, high-power density, and multiple protection features. The MP3332 supports flash, assist, torch, indicator, and 5V DC modes. To improve thermal performance, the cathodes of the dual flash LED are referenced to GND for a better layout. It is available in a WLCSP-16 (1.7mmx1.7mm) package.
