The G5111 boost converter is designed for small/ me-dium size LCD panel of high bias voltage.

Due to a typical 20A quiescent current and 2.5V~6.5V supply voltage range, G5111 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 1A.

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. G5111 typically consumes less than 1A of full supply range.
