The TPS65100PWP is a compact Power Supply IC that provides all three voltages required by thin film transistor (TFT) LCD displays. The auxiliary linear regulator controller can be used to generate a 3.3V logic power rail for systems powered by a 5V supply rail only. The main output, VO1, is a 1.6MHz, fixed-frequency PWM boost converter providing the source drive voltage for the LCD display. The device is available in two versions with different internal switch current limits to allow the use of a smaller external inductor when lower output power is required. The device has a typical switch current limit of 2.3A. The device has a linear regulator controller using an external transistor to provide a regulated 3.3V output for the digital circuits.
