• Manufacturer Part Number: S1F78100Y2A
• Description: High Precision Voltage Regulators
• Manufacturer: Epson Electronics America, Inc.

S1F76610 Series CMOS DC/DC Converter (Voltage
Doubler / Tripler) & Voltage Regulator
DESCRIPTION
The S1F76610 Series is a highly effecient CMOS DC/
DC converter for doubling or tripling an input voltage.
It incorporates an on-chip voltage regulator to ensure
stable output at the specified voltage. The S1F76610
Series offers a choice of three, optional temperature
gradients for applications such as LCD panel power
supplies.
The S1F76610C0B0 is available in 14-pin plastic DIPs,
the S1F76610M0B0, in 14-pin plastic SOPs, and the
S1F76610M2B0 in 16-pin plastic SSOPs.
FEATURES
• 95% (Typ.) conversion efficiency
• Up to four output voltages, V
• On-chip voltage regulator
• 20mA maximum output current at V
• Three temperature gradients : –0.1, –0.4 and –0.6%/
