Product Summary

The MAX1889ETE-T is a Triple-Output TFT LCD Power Supply with Fault Protection. It provides the three regulated output voltages required for active matrix, thin-film transistor liquid crystal displays (TFT LCDs). The MAX1889ETE-T combines a high-performance step-up regulator with two linear-regulator controllers and multiple levels of protection circuitry for a complete power-supply system. The MAX1889ETE-T has a unique input switch control that can replace the typical input fuse by disconnecting the load from the input supply when a fault is detected. The applications of the MAX1889ETE-T are Notebook Computer Displays, LCD Monitors, Car Navigation Displays.
