The EV3371-R-00A is an evaluation board designed for the MP3371, a synchronous boost converter with eight current channels designed to drive WLED arrays for LCD panels in tablets and notebook backlighting applications.
The MP3371 uses peak current mode and pulse-width modulation (PWM) control to regulate the boost converter. The MP3371 employs a standard I2C digital interface to set the operation mode, switching frequency, fullscale current for each channel, sync or nonsync mode, dimming mode and duty, and various protection thresholds.
The MP3371 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 MP3371 is available in a QFN-24 (4mmx4mm) package.
