S-8813 Series
www.sii-ic.com
Rev.3.0_00
© Seiko Instruments Inc., 2002-2010
The S-8813 Series is a PFM control charge pump DC-DC converter with a built-in constant-current circuit, and
was developed using CMOS technology. Its constant current output makes this series ideal as a power supply for
current drive LEDs.
The S-8813 Series features three output channels and can drive three LEDs.
This series is available in two types: a variable voltage type and a variable current setting resistance type.
Moreover, since small ceramic capacitors can be used as external capacitors (pump capacitors, input capacitors,
output capacitors), the S-8813 Series contributes to set miniaturization.
