S6A0092
26 COM / 80 SEG DRIVER & CONTROLLER FOR STN LCD
VOLTAGE CONVERTER
The Voltage Converter circuit generates positive 4 times voltage of 1.8V that is generated internally. VOUT is
generated from the voltage converter. And this conversion voltage is used in the built-in Voltage Regulator circuit.
This application circuit is same as 3 times DC/DC converter.
