Аппаратные драйверы ЖКД TPS65100QPWPRQ1

Источник питания TFT ЖК-дисплея с линейным стабилизатором , 2.7В до 5.8В вход, HTSSOP-24

The TPS65100QPWPRQ1 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.
