Analog Devices / Maxim Integrated MAX25540 Automotive Display Power Solution

Analog Devices MAX25540 Automotive Display Power Solution is designed to accommodate the main rails used in modern automotive TFT displays. The IC supports the power requirement of GMSL parts. The MAX25540 and MAX25530 TFT power supply and LED backlight driver provide a two-chip solution to automotive display power supply requirements. The Analog Devices 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.
