S1F76610 Series

S1F76610 Series CMOS DC/DC Converter (Voltage Doubler / Tripler) & Voltage Regulator

DESCRIPTION

The S1F76610 Series is a highly effecient CMOS DC/

External shut-down control

DC converter for doubling or tripling an input voltage.

2μA maximum output current when shut-down

It incorporates an on-chip voltage regulator to ensure

Two-in-series configuration doubles negative output

stable output at the specified voltage. The S1F76610
