Description

General part information

MP3318 Series

MP3318 is a WLED step-up converter with three current sinks and a 2.7 to 5.5V power supply input. The MP3318 uses peak-current mode to regulate the LED current set by the internal register. It integrates a 250mohm, 42V MOSFET. The maximum LED voltage is up to 38V. MP3318 is able to drive 10 LEDs in series for LCD panel applications larger than 5". It supports both linear and exponential analogue dimming with 11bit, ultra-high resolution to accurately regulate dimming current. Its auto-switching frequency function can optimize efficiency performance. Full protection features include LED open and short protection, cycle-by-cycle current limit and thermal shutdown. The I2C interface can set the internal register to program the MP3318 for flexible applications such as dimming mode, LED current ramp and protection threshold. It is available in a tiny WLCSP-12 (1.3mmx1.7mm) package. Applications include smartphones, tablets, GPS receivers, LCD video displays with one-cell Li-Ion battery.
