Product Information

The MP3376A is a synchronous boost converter with eight current channels designed to drive WLED arrays for LCD panels in tablets and notebook backlighting applications.

The MP3376A uses peak-current-mode and pulse-width modulation (PWM) control to maintain boost converter regulation. The MP3376A employs a standard I2C digital interface to set the operation mode, switching frequency, full-scale current for each channel, sync or non-sync mode, dimming mode and duty, and various protection thresholds.

The MP3376A features high efficiency due to low-headroom voltage for LED regulation and a small on resistance of the switching MOSFET. The synchronous rectifier saves PCB size and total BOM cost.

The MP3376A is available in a QFN-24 (4mmx4mm) package.

Applications:
• Tablets/Notebooks
• Automotive Displays
