3-CHANNEL WHITE LED DRIVER IC
(CHARGE PUMP IC WITH BUILT-IN CONSTANT-CURRENT CIRCUIT)
S-8813 Series
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.
