SS8051

Micro-Power Step-up DC/DC Converter

FEATURES

DESCRIPTION

The SS8051 boost converter is designed for small to

medium size LCD panels requiring high bias voltages.

Configurable output voltage up to 28V

Quiescent current of 20µA

Shutdown current <1µA

Shutdown-pin current <1µA

Supply range from 2.5V to 6.5V

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

Tiny SOT23-5 package

With a typical quiescent current of 20µA and a supply

voltage range of 2.5V to 6.5V, it is suitable for battery

powered portable applications, such as PDAs and

handheld computers. When the SS8051 goes into

shutdown mode, it consumes less than 1µA.

Furthermore, with a 350mA current limit, 500ns fixed

minimum off-time and tiny SOT23-5 package, the

SS8051 can be used with smaller inductors and other

surface-mount components to minimize the required PCB

footprint in space-conscious applications.

APPLICATIONS

STN/TFT LCD Bias

Personal Digital Assistants (PDAs)

Handheld Computers

Digital Still Cameras

Cellular Phones

To control the SS8051, no other external current is

needed for the shutdown pin, which typically consumes

less than 1µA over the full supply range.
