Technical Manual
S1F76600
Series
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, VO, relative to VDD and VI
• 30mA maximum output current at 5V
• Connecting-in-series configuration obtains a higher
output voltage (V1=–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

Notes:
1. The recommended circuit configuration for low-voltage operation (when VIis between –1.2V and
–2.2V) is shown in the following figure. Note that diode D1 should have a maximum forward voltage of
0.6V with 1.0mA forward current.
2. RLmin can be varied depending on the input voltage.
