Product Details

The MAX8790A evaluation kit (EV kit) is a fully assembled and tested surface-mount PCB that evaluates the high-efficiency MAX8790A white LED (WLED) driver. The MAX8790A EV kit utilizes a step-up DC-DC converter to generate the voltage required to drive up to six strings of eight surface-mount WLEDs. The EV kit is powered by a 7V to 21V input power supply (single-supply mode) and can be configured to provide a fixed 20mA or adjustable 15mA to 25mA full-scale LED current. In addition, the MAX8790A provides LED current control through either analog or digitally adjusted pulse-width modulation (DPWM) dimming modes. As shipped, the MAX8790A EV kit is configured for evaluation with two strings of eight WLEDs.
