www.DataSheet4U.com SM8130 series White LED Driver IC OVERVIEW The SM8130 series are a doubler charge pump DC/DC converter with built-in constant current circuit (independent 3ch).

Stable output supply can be realized by an input series regulator and an output side charge pump.

1 to 3 lights of white LED connected in parallel can be lighted.

Current variation among LED is reduced due to the independent 3ch constant circuit.

Current value sent to white LED can be set by supply level of CONT pin
