MP3312LGC-P

The MP3312L is a dual-channel, step-up WLED driver with an integrated 40V MOSFET. It supports a 2.7V to 5.5V power supply input and uses peak current mode to regulate the LED current, which is set by an external resistor. The MP3312L employs a 600kHz fixed switching frequency. It supports both PWM input analog dimming and digital analog dimming to regulate the dimming current accurately. The MP3312L integrates a current source to balance the LED current, which leads to good ILED matching and accuracy performance. In addition, the MP3312L has both LED open and short protection, cycle-by-cycle current limit protection, and thermal shutdown protection. It is available in a tiny WLCSP1.35x1.35-9mm package.
