Monolithic Power Systems (MPS) MP3332 Dual Channel LED Photo Flash Drivers
Monolithic Power Systems (MPS) MP3332 Dual Channel LED Photo Flash Drivers are ideal for high-resolution cameras on smartphones. The compact drivers are highly efficient at improving the image and video quality in low-light environments. A synchronous boost converter operates at 1MHz to 4MHz for 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 LED lighting drivers support flash, assist, torch, indicator, and 5VDC modes. Applications for MPS MP3332 Dual Channel LED Photo Flash Drivers include LED flash for smartphones, cameras for tablets, and digital still cameras.
