EV3318-C-00A

EV3318-C-00A is an evaluation board for the MP3318, a white LED step-up driver with a 2.7V to 5.5V input voltage range and 3-channel current sinks. MP3318 uses peak current control mode to regulate LED current set by an internal register. The MP3318 integrates a 250mohm, 42V MOSFET with a 38V maximum LED voltage output. IC has the ability to drive LEDs in series for <gt/>5” LCD panel applications. The IC’s automatic switching frequency function optimizes efficiency. In addition, the MP3318 offers LED open protection, LED short protection, cycle-by-cycle current limit protection, overvoltage protection and thermal shutdown. I2C interface can set the internal register to program the MP3318 for flexible applications such as dimming mode, LED current ramp, and featured protection functions. The MP3318 is available in an ultra-small WLCSP-12 (1.3mmx1.7mm) package. Applications include smartphones, tablets, GPS receivers, liquid crystal displays (LCDs) with singlecell lithium-ion batteries.
