The EV3312-C-00A is an evaluation board for the MP3312, a dual-channel, step-up WLED driver with an integrated 40V MOSFET. It supports a power supply input range of 2.7V to 5.5V. It uses peak current mode to regulate the LED current, which is set by an external resistor. The MP3312 employs a 1.2MHz fixed switching frequency. It features supporting both PWM input analog dimming and digital analog dimming to accurately regulate the dimming current. The MP3312 integrates current source to balance LED current, which leads to good ILED matching and accuracy performance.
In addition, the MP3312 has LED open and short protection, cycle-by-cycle current limit protection, and thermal shutdown protection. It is available in a tiny WLCSP-9 (1.3mmx1.3mm) package.
