Monolithic Power Systems (MPS) EVQ3326-R-00A LED Driver Evaluation Board

Monolithic Power Systems (MPS) EVQ3326-R-00A LED Driver Evaluation Board is designed for the MPQ3326. The MPQ3326 is a 16-channel WLED driver that can operate from a wide 4V to 16V input voltage range. The MP3326 applies 16 internal current sources in each LED string terminal. An external current setting resistor sets the LED current of each channel. The maximum current for each channel is 50mA (VIN ≥ 4.5V).

The Monolithic Power Systems (MPS) EVQ3326-R-00A LED Driver Evaluation Board features a pre-installed MPQ3326 WLED Driver in a compact QFN-24 package. The evaluation board is designed to connect to the EVKT-USBI2C-02 USB to I²C/PMBus Dongle, which in turn connects to a Microsoft Windows-based PC. An I²C Graphic User Interface (GUI) provides an easy-to-use interface for demonstrating the features of the MPQ3326 WLED Driver.
