Product Details

The MAX16923 evaluation kit (EV kit) is a fully assembled and tested surface-mount PCB used to evaluate the MAX16923 automotive 4-output display-power solution. The MAX16923 is a 4-channel power-management IC designed to accommodate the main rails used in modern automotive TFT displays. The MAX16923 integrates a high-voltage buck converter that transforms battery voltages into a 5V or 3.3V intermediate rail. In addition, a high-voltage, always-on, low-quiescent-current linear regulator supplies power at 3.3V. The low-voltage section consists of a fully-integrated DC/DC converter and an LDO running off the intermediate rail. A single START control pin initiates the start-up sequence, thereby simplifying device control. The MAX16923’s external PMOSFET control block allows battery voltage to be switched to a downstream device, such as a backlight boost converter. The MAX16923 also embeds a watchdog timer and selectable switching frequencies with spread spectrum.
