The MP3376 is a synchronous boost converter with 8 current channels designed to drive WLED arrays for LCD-panel in tablet and notebook backlighting applications.
The MP3376 uses peak-current mode and PWM control to maintain boost converter regulation. The MP3376 employs a standard I2C digital interface to set operation mode, switching frequency, full-scale current for each channel, sync or non-sync mode, dimming mode and duty, and various protection thresholds.
MP3376 features high efficiency with small on resistance of switching MOSFET. In addition, the synchronous rectifier saves PCB size and total BOM cost.
The MP3376 is available in QFN24 (4mmX4mm) package.
