MP3331 Synchronous Boost Flash LED Drivers
Monolithic Power Systems (MPS) MP3331 Synchronous Boost Flash LED Drivers with an I2C interface are designed for high-resolution camera phones. These highly efficient, 2A, single-flash LED drivers improve image and video quality in low-light environments. The MP3331 series operates in a 1MHz/2MHz/3MHz/4MHz synchronous DC-DC boost converter to deliver an optimized solution for smaller PCB spaces with higher efficiency. Features include rich protection modes, high power density and performances, and flash / assist light / torch / indicator / 5V DC modes. The cathode of the flash LED is referenced to GND, which improves thermal performance. MPS MP3331 Synchronous Boost Flash LED Drivers are available in a 1.7mm x 1.7mm WLCSP9 package. The MP3331 series is ideally suited for use in phone camera LED flash applications, tablets, and digital still cameras.
