Maxim Integrated / Analog Devices MAX25512EVKIT# MAX25512EVKIT# Evaluation Kit MAX25512ATG/V+ 4 Channel High-Brightness LED Driver

MAX25512 evaluation kit (EV kit) demonstrates the MAX25512, integrated 4-channel high-brightness LED driver with I2C interface for automotive displays. The EV kit operates from a DC supply voltage between 3V and 36V and the switching frequency can be set at either 2.2MHz or at 400kHz. The EV kit can only be configured to operate in I2C 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 PWM dimming. Dimming can be performed either externally using a PWM signal applied to the DIM PCB pad or internally by programming the desired dimming frequency and individual duty cycle through I2C. The hybrid dimming feature can be enabled through a register bit to reduce EMI. The EV kit features a LED current foldback option either as a function of the temperature, by means of an on-board NTC sensor, or through an analogue dimming register. I2C-programmable automatic fading functionality is also available.
