MAX25540GTP/V+

MAX25540GTP/V+ is a 4-channel power-management IC designed to accommodate the main rails used in modern automotive TFT displays. The IC supports the power requirement of GMSL parts. The TFT power supply and LED backlight driver combine to provide a two-chip solution to automotive display power supply requirements. This 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 an LDO running off the intermediate rail. The low-voltage DC/DC converter provides 1V, while the LDO produces 1.8V. Application includes infotainment displays, central information displays, and instrument clusters.
