SM8610CV
Laser Switching Driver IC
OVERVIEW
The SM8610CV is a portable CD player laser driver IC. It uses a laser switching drive that reduces the laser
power dissipation, thereby reducing data read current consumption and extending battery life significantly,
when compared with existing devices which use a constant-current laser control method with corresponding
high dissipation which places limits on battery life.
