Analog Devices / Maxim Integrated MAX20446C Evaluation Kit

Analog Devices Inc. MAX20446C Evaluation Kit demonstrates the MAX20446C 6-channel high-brightness LED driver with boost controller for automotive displays. The kit operates from a DC supply voltage between 4.5V and 36V. The switching frequency can be set at 2.2MHz or at 400kHz. This ADI kit operates in stand-alone mode. Spread-spectrum mode is enabled by default for EMI improvement.
