TPS65105 - Texas Instruments

TPS65105 Triple Output LCD Supply

The TPS6510x series offers a compact 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 conver.
