Product Details
The MAX20056B evaluation kit (EV kit) demonstrates the MAX20056B, an integrated, 6-channel high-brightness LED driver with very wide PWM dimming ratio and phase shifting for automotive displays.
The EV kit operates from a DC supply voltage from 4.5V to 36V and the switching frequency is set at 400kHz. Spread-spectrum mode (SSM) is enabled for EMI improvement. The EV kit demonstrates direct dim and phase-shifted pulse-width modulation (PWM) dimming. The EV kit also demonstrates short-LED, open- LED, and overtemperature-fault protection.
For operation at switching frequencies other than 400kHz, the external components should be chosen according to the calculations in the MAX20056B IC data sheet.
Applications
- Automotive Central Information Displays
- Automotive Dashboards
- Automotive Head-Up Displays
- Automotive Navigation Systems
