General Description
The G5111 boost converter is designed for small/ me-
dium size LCD panel of high bias voltage.
Due to a typical 20μA quiescent current and
2.5V~6.5V supply voltage range, it is suitable for bat-
tery powered portable applications. Such as PDAs and
Handheld Computers. When the IC sets to shutdown
mode, it only consumes less than 1μA.
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
1μA of full supply range.
