About This Product

■Summary

The MP3318 is a white LED step-up converter with three current sinks and a 2.7 to 5.5V power input. MP3318 uses peak current mode to adjust the LED current set by internal registers. The MP3318 has an integrated 250mΩ, 42V MOSFET. The maximum voltage of LED is up to 38V. The MP3318 can drive 10 LEDs in series for LCD panel applications larger than 5 inches. The MP3318 supports both linear and exponential analog dimming with 11-bit ultra-high resolution and precisely adjusts the dimming current. Automatic frequency switching feature allows you to optimize efficiency performance. Extensive protection features include LED open and short protection, cycle-by-cycle current limit protection, and thermal shutdown. An I2C interface allows internal registers to be set to program the MP3318 with dimming modes, LED current ramps, protection thresholds, etc. for flexible applications. The MP3318 is available in a small WLCSP-12 (1.3mm x 1.7mm) package.
