AK2559 Datasheet (AKM) - 2ch Cathode Common LDD

AK2559, 2ch Cathode Common LDD

The AK2559 is a 2-channel cathode common LDD (Laser Diode Driver) suitable for MFPs (Multi Function Printer) and LBPs (Laser Beam Printer).

The AK2559 equips a 200MHz [Max.] LDD that switches the LD current, current-DACs that set the operation current of LD and a feed-back digital APC (Auto Power Co
