DESCRIPTION
AIC1533, composed of dual charge pumps and a
regulator, provide three independent regulated
voltages designed for using in thin-film transistor
(TFT) liquid crystal display (LCD).
The main regulator has an adjustable output
voltage and a low dropout voltage of 500mV at
300mA load current is performed.
The dual charge pumps independently regulate a
positive output and a negative output. AIC1533
has thermal shutdown capability and survives a
continuous short circuit from output to ground. A
unique control scheme minimizes output ripple as
well as output capacitance for both charge pump.
1MHz-switching frequency of AIC1533 provides a
low noise, low cost total solution. The device
operates up to 15V supply voltage and is available
in 14-lead SOP and 16-lead TSSOP package.
