MAX25561EVKITA# Evaluation Kit
Analog Devices Inc. MAX25561EVKITA# Evaluation Kit demonstrates the MAX25561 integrated 6-channel high-brightness LED driver with a boost controller and I2C interface for automotive displays supporting ASIL B. The EV kit operates from a DC supply voltage of 7V (4.5V if the LED current per string is set to 150mA or less) to 36V, and the switching frequency can be either 2.2MHz or 400kHz. The EV kit can only be configured to operate in I2C mode. Spread-spectrum mode (SSM) is enabled by default for EMI improvement, but it can be disabled by acting on a register bit. The EV kit demonstrates phase-shifted, pulse-width modulation (PWM) dimming. The hybrid dimming feature can also be enabled through a register bit to reduce EMI.
