ETC G5113

G5113
Global Mixed-mode Technology Inc.
Micro-power Step-Up DC/DC Converters in SOT23-5
Features
General Description
„Configurable Output Voltage Up to 35V
„20µA Quiescent Current
„<1µA Shutdown Current
„<1µA Shutdown Pin Current
„Supply Rage from 2.5V to 7V
„Low VDSSAT: 200mV (ISW=200mA)
„Tiny SOT23-5 Package
The G5113 boost converter is designed for small/
medium size LCD panel of high bias voltage.
Applications
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.
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.
„STN/TFT LCD Bias
„Personal Digital Assistants (PDAs)
„Handheld Computers
„Digital Still Cameras
„Cellular Phones
„WebPad
„White LED Driver
„Local 3V to 5V Conversion
To control the IC, no other external current is needed
for the shutdown pin. It typically consumes less than
1µA of full supply range.
