TPS65100QPWPRQ1

与线性稳压器和VCOM缓冲器三输出LCD电源 TRIPLE-OUTPUT LCD SUPPLY WITH LINEAR REGULATOR AND VCOM BUFFER

The 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 5-V 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. A fully integrated adjustable charge pump doubler/tripler provides the positive LCD gate-drive voltage. An externally adjustable negative charge pump provides the negative gate-drive voltage. The device can be enabled again by toggling the input or the enable EN pin to GND.
