www.DataSheet.co.kr Rev.2.1_00 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.
