Monolithic Power Systems (MPS) EV3318-C-00A Evaluation Board
Monolithic Power Systems (MPS) EV3318-C-00A Evaluation Board provides a demonstration platform for the MP3318 3-Channel WLED Driver. The MP3318 is a step-up converter with three current sinks and a 2.7V to 5.5V power supply input. The MP3318 uses peak-current mode to regulate the LED current set by the internal register. The MP3318 integrates a 250mΩ, 42V MOSFET. The maximum LED voltage is up to 38.0V. The MP3318 can drive up to 10 LEDs in series for LCD panel applications larger than 5".
The Monolithic Power Systems (MPS) EV3318-C-00A Evaluation Board features a pre-installed MP3318 3-Channel WLED Driver in a 1.3mm x 1.7mm WLCSP-12 package. An I2C interface Graphic User Interface (GUI) enables the user to configure the MP3318 with options such as dimming mode, LED current ramp, and protection threshold.
