Monolithic Power Systems (MPS) EV3383-S-00A WLED Controller Evaluation Board
Monolithic Power Systems (MPS) EV3383-S-00A WLED Controller Evaluation Board is designed to demonstrate the capabilities of the MP3383, a step-up controller with four LED current channels. This board features a 6V to 33V input voltage range, 4LED strings, 400mA/channel maximum LED current, and maximum <80V output voltage. The protection features include Over-Voltage Protection (OVP), Over-Temperature Protection (OTP), short inductor, and diode protection. The MP3383 WLED controllers employ peak current control mode with a fixed Switching Frequency (fSW) that is configurable through an external setting resistor. Typical applications include desktop LCD flat-panel displays, all-in-one PCs, and 2D and 3D LCD TVs.
