1 / 9 page  www.SiliconStandard.com 1 of 9 SS8028 Micro-Power Step-up DC/DC Converter FEATURES Configurable output voltage up to 16V Quiescent current of 20µA Shutdown current <1µA Shutdown-pin current <1µA Supply range from 2.5V to 6.5V Low V DS(on): 250mV (ISW=300mA) Tiny SOT-23-5 package 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 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.
