General Description
The G5122 inverting DC/DC converter is designed for
small/ medium size LCD panel of high bias voltage.
Due to a typical 20A quiescent current and 2.5V~
6.5V supply voltage range, it is suitable for battery
powered portable applications. Such as PDAs and
Handheld Computers. When the IC sets to shutdown
mode, it only consumes less than 1A.
Furthermore, the 350mA current limit, 500ns fixed
minimum off-time and tiny SOT23-5 package facili-
tates the use of smaller inductor and other sur-
face-mount components to minimize the PCB size in
those space-conscious applications.
To control the IC, no other external current is needed
for the shutdown pin. It typically consumes less than
1A of full supply range.
