MAX20446CEVKIT#

MAX20446C evaluation kit (EV kit) demonstrates the MAX20446C, an integrated 6-channel high-brightness LED driver with boost controller for automotive displays. The EV kit operates from a DC supply voltage between 4.5V and 36V, and the switching frequency can be either set at 2.2MHz or at 400kHz. The EV kit operates in stand-alone mode. Spread-spectrum mode is enabled by default for EMI improvement. The EV kit demonstrates phase-shifted pulse-width modulation (PWM) dimming. Dimming can be performed externally using a PWM signal applied to the DIM PCB pad. The hybrid dimming feature can also be enabled through a resistor connected between the SET pin and GND to reduce EMI. The EV kit also demonstrates short-LED, open-LED, boost output undervoltage and overvoltage, and overtemperature-fault protection.
