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.
