The MAX6948 EV kit boost converter drives 6 high-brightness white LEDs in series with 30mA (typ). The boost converter features 10-bit PWM dimming, standby mode, input current limit, and overvoltage protection.
The MAX6948 EV kit’s I/O ports drive LEDs or act as open-drain GPIO port expanders. Jumpers easily switch between the two functions. The ports feature selectable constant-current sinking, fading, and 8-bit PWM.
