General Description
The G5104 boost converter is designed for 3.3V/5V
powered system.
Due to a typical 40µA quiescent current and 1.7V~
5.5V 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 500mA current limit, 450ns 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. It typically consumes less than
1µA of full supply range.
