The MAX17127 evaluation kit (EV kit) is a fully assembled
and tested surface-mount PCB that evaluates the high-
efficiency MAX17127 white LED (WLED) driver. The EV
kit utilizes a step-up DC-DC converter to generate the
voltage required to drive up to six strings of 10 surface-
mount WLEDs. The EV kit uses a 5V to 26V input power
supply and can be configured to provide an adjustable
10mA to 30mA full-scale LED current.
