Description

The MAX8678 evaluation kit (EV kit) is a fully assembled and tested printed-circuit board (PCB) for evaluating the MAX8678 white LED charge pump with mono class AB audio amplifier. The MAX8678 EV kit drives up to four LEDs for backlighting. In addition, the EV kit is able to drive a combined loudspeaker/earpiece speaker for the mono audio amplifier. An on-board pulse generator provides an easy way to evaluate the MAX8678's amplifier gain adjustment and LED dimming.
