The EV3372-R-00A is an evaluation board for the MP3372, a synchronous boost converter with eight current channels. The IC is designed to drive WLED arrays for LCD panels in tablets and notebook backlighting applications.
The MP3372 uses peak current mode and pulse-width modulation (PWM) control to regulate the boost converter. The MP3372 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 low-headroom voltage for LED regulation and small on resistance of the switching MOSFET provide the MP3372 with high efficiency. The synchronous rectifier saves PCB size and total BOM cost.
The MP3372 is available in a QFN-24 (4mmx4mm) package.
