Product Details

The MAX20051 evaluation kit (EV kit) demonstrates the MAX20051 and MAX20053, 2A synchronous buck LED drivers with integrated MOSFETs.

The EV kit operates from a DC supply voltage from 4.5V to 65V and the switching frequency is fixed at 400kHz. Spread-spectrum mode (SSM) is enabled for EMI improvement. The EV kit demonstrates both analog and pulse-width modulation (PWM) dimming. The EV kit also demonstrates short LED, open LED, and overtemperature- fault protection.

The EV kit also comes with a MAX20053 IC, which can be installed to evaluate the 2.1MHz switching frequency device. Refer to the Evaluating the MAX20053 section for more information.
