The MAX16809 evaluation kit (EV kit) is a 16-channel, constant-current LED driver, capable of driving 40mA each to 16 LED strings with a total forward voltage of up to 32V. The MAX16809 EV kit is based on the MAX16809 device, which has 16 constant-current-sinking outputs with sink current settable using a single resistor and a high-performance, current-mode pulse-width-modulator (PWM) controller, for implementing a DC-DC converter that generates the supply voltage to drive the LED strings.
The MAX16809 EV kit operates at supply voltages between 9V to 16V and temperatures ranging from 0°C to +70°C. It features a PWM dimming control, adaptive control of the LED supply voltage, which depends upon the operating voltage of the LED strings, a built-in clock generator, and a low-current shutdown. The MAX16809 EV kit is a fully assembled and tested
board.
