GENERAL DESCRIPTION

The ADM8830 is a charge pump regulator used for color thin film transistor (TFT) liquid crystal displays (LCDs). Using charge pump technology, the device can be used to generate three output voltages (+5.1 V ± 2, +15.3 V, –10.2 V) from a single 3 V input supply. These outputs are then used to provide supplies for the LCD controller (5.1 V) and the gate drives for the transistors in the panel (+15.3 V and –10.2 V). Only a few external capacitors are needed for the charge pumps. An efficient low dropout voltage regulator also ensures that the power efficiency is high and provides a low ripple 5.1 V output. This LDO can be shut down and an external LDO used to regulate the 5 V doubler output and drive the input to the charge pump section, which generates the +15.3 V and –10.2 V outputs if so required by the user.
