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
