Product Summary

The TPS65140RGER is a triple output LCD supply with linear regulator and power good. The TPS65140RGER offers a compact and small power supply solution to provide all three voltages required by thin film transistor (TFT) LCD displays. The auxiliary linear regulator controller can be used to generate a 3.3-V logic power rail for systems powered by a 5-V supply rail only. The main output Vo1 is a 1.6-MHz fixed frequency PWM boost converter providing the source drivevoltage for the LCD display. The applications of the TPS65140RGER include TFT LCD Displays for Notebooks, TFT LCD Displays for Monitors, Portable DVD Players, Tablet PCs, Car Navigation Systems, Industrial Displays.
