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

S1F76620 Series
S1F76620 Series CMOS DC/DC Converter (Voltage Doubler)
DESCRIPTION
S1F76620 is a high efficiency and low power consump-
tion CMOS DC/DC converter. It enables to obtain 2
times step-up output (3.0 to 16V) from input voltage
(1.5 to 8V). Also, S1F76620 enable to drive ICs (liquid
crystal driver, analog IC, etc.), which require another
power supply in addition to logic main power supply,
with a single power supply, and it is suitable for micro
power IC of hand-held computers, handy devices, etc.
due to its small power consumption.
