1. DC/DC Converter
S1F76600 Series
S1F76600 Series CMOS DC/DC Converter (Voltage Doubler)
DESCRIPTION
The S1F76600 Series is a highly efficient CMOS DC/
DC converter for doubling an input voltage (from
–1.5V to –8V). 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 S1F76600C0B0 is available in 8-pin plastic DIPs,
and the S1F76600M0B0, in 8-pin plastic SOPs.
FEATURES
• 95% (Typ.) conversion efficiency
• Two output voltages, V
O, relative to VDD and VI
• 30mA maximum output current at 5V
• Connecting-in-series configuration obtains a higher
output voltage (V
1=–5V, V0=–15V at two-in-series).
• Low operating voltage
• On-chip CR 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
