Laser Switching Driver IC

OVERVIEW

The SM8613AV is a portable CD player laser diode (LD) driver IC. Conventional portable CD players use a

ﬁxed-current LD drive method, but this increases the power dissipation and limits battery life. The SM8613AV

employs an intermittent LD driver duty operation to reduce the laser power dissipation, which greatly reduces

the current consumption when reading data and extends battery driver life.
