SM8120A

White LED Driver IC

OVERVIEW

The SM8120A is a high efﬁciency step-up DC/DC converter. Due to high voltage CMOS process realizing

24V output supply as maximum value, white LED of 2–4 lights connected in series can be lighted. By connect-

ing in series, current variation among LED is eliminated. Current value sent to white LED can be set by exter-

nal resistors. In addition, brightness can also be adjusted by control to FB pin or CE pin.
