About This Product

■Summary

The MP3336A is a compact dual-channel high-power flash LED driver that can drive up to 2A in flash mode for each LED. MP3336A improves image and video quality in low light environments for camera phones. The MP3336A operates with selectable 1/2/3/4MHz switching frequencies and uses a synchronous rectification, current mode PWM boost converter to regulate LED current with two high current sources. MP3336A provides a highly efficient and optimized solution for smaller PCB space. MP3336A features a standard I2C interface, dual LED channels, rich protection modes, and high power density and high performance. MP3336A can also support flash, assist, indicator, and 5V DC modes. The cathode of the dual flash LED is referenced to GND, which improves thermal performance in the layout. The MP3336A is offered in a WLCSP-20 (1.6mm x 2.0mm) package.

■Features and benefits
