G5111

Micro-power Step-Up DC/DC Converters in SOT-23-5

Features

General Description

Configurable Output Voltage Up to 28V

The G5111 boost converter is designed for small/ me-

dium size LCD panel of high bias voltage.

20µA Quiescent Current

<1µA Shutdown Current

<1µA Shutdown Pin Current

Supply Range from 2.5V to 6.5V

Low V_DS(on): 250mV (I_SW=300mA)

Tiny SOT-23-5 Package

Due to a typical 20µA quiescent current and 2.5V~

6.5V 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 350mA current limit, 500ns fixed

minimum off-time and tiny SOT-23-5 package facili-

tates the use of smaller inductor and other sur-

face-mount components to minimize the PCB size in

those space-conscious applications.

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

To control the IC, no other external current is needed

for the shutdown pin. It typically consumes less than

1µA of full supply range.
