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 APPLICATIONS • Fixed-voltage power supplies for battery-operated equipment • Power supplies for pagers, memory cards, calculators and similar hand-held equipment • Fixed-voltage power supplies for medical equipment • Fixed-voltage power supplies for communications equipment • Uninterruptable power supplies
