The MP3332 is a dual-channels flash LED driver with very compact package, high efficiency for high-resolution camera phones to improve image and video quality in low light environment. The synchronous boost converter operates in 1/2/3/4MHz to provide an optimized solution for smaller PCB space and higher efficiency.
The MP3332 features standard I2C interface, dual LED channels, rich protection modes and high power density and performances. The MP3332 supports flash/assist light/torch/indicator/5V DC modes.
The cathodes of the dual flash LED are referenced to GND for better layout to improve thermal performance. It is available in WLCSP16-1.65X1.65mm package.
