DESCRIPTION

The SCI7660 Series is a highly efficient CMOS DC/DC converter for doubling an input voltage. This power saving IC allows portable computers and similar hand held equipment to operate from a single power supply, even when they incorporate LSIs that operate at voltages different from those of logic circuits, for example, LCD drivers and analog LSIs.

The SCI7660C0B is available in 8-pin plastic DIPs, and the SCI7660M0B, in 8-pin plastic SOPs.

FEATURES

• 95 (typ.) conversion efficiency

• Two output voltages, VO, relative to VDD and VI

• 30mA maximum output current at 5V

• Two-in-series configuration doubles negative output voltage.

• Low operating voltage

• On-chip RC oscillator

• 8-pin plastic DIP and 8-pin plastic SOP
