DESCRIPTION
   The MP3336 is a dual-channel and high-power flash LED driver with very compact package. It can drive up to 2A in flash mode for each LED. It is usually applied for camera phones to improve image and video quality in low light environment. The device operates in1/2/3/4MHz synchronous, current-mode PWM boost converter to regulate the LED current with two high current source. The MP3336 provides an optimized solution for smaller PCB space and higher efficiency.
