DESCRIPTION

The SS8028 boost converter is designed for small and

medium size LCD panels requiring high bias voltages.

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 SS8028 goes into

shutdown mode, it consumes less than 1µA.

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

minimum off-time and tiny SOT-23-5 package, the

SS8028 can be used with smaller inductors and other

surface-mount components to minimize the required PCB

footprint in space-conscious applications.

To control the SS8028, no other external current is

needed for the shutdown pin, which typically consumes

less than 1µA over the full supply range.
