MAX25540EVKIT#

MAX25540EVKIT# is a MAX25540 evaluation kit (EV kit) is a fully assembled and tested surface-mount PCB used to evaluate MAX25540 automotive 4-output display-power solution. MAX25540 is a 4-channel power management integrated circuit designed to accommodate the main rails used in modern automotive thin-film transistor (TFT) displays. The MAX25540 integrates a high-voltage buck converter that transforms battery voltages into a 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 a low dropout (LDO) running off the intermediate rail. Low-voltage DC/DC converter provides 1V, while the LDO produces 1.8V. A single START control pin initiates the start-up sequence, thereby simplifying device control. The MAX25540’s external PMOSFET control block allows battery voltage to be switched to a downstream device, such as a backlight boost converter.
