TPS65140 Overview
The TPS6514x series offers a pact 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 drive voltage for the LCD display.
