www.DataSheet4U.com SM8613AV 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. FEATURES I I PINOUT (Top view) I I I I I I 2.3V low-voltage supply operation Intermittent-duty laser driver built-in (4-times speed read, 38MHz max. intermittent output) Laser switching frequency range: 8.
