General Description
The G5113 boost converter is designed for small/
medium size LCD panel of high bias voltage.
Due to a typical 20µA quiescent current and 2.5V~7V
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 1µA.
Furthermore, the 250mA current limit, 400ns fixed
minimum off-time and tiny SOT23-5 package facilitates
the use of smaller inductor and other surface-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.
