General Description
The G5113 boost converter is designed for small/
medium size LCD panel of high bias voltage.
Due to a typical 20碌A(chǔ) 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 1碌A(chǔ).
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
1碌A(chǔ) of full supply range.
Applications
STN/TFT LCD Bias
Personal Digital Assistants (PDAs)
Handheld Computers
Digital Still Cameras
Cellular Phones
WebPad
White LED Driver
Local 3V to 5V Conversion
