TPS65105 Overview
The TPS6510x series offers a pact and small power supply solution that provides 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.
