AK2559 Datasheet PDF

Asahi Kasei Microdevices AK2559

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 Control) circuit that maintains the optical LD power constant. The AK2559 can improve the printing quality and reduces external parts and the cost with useful functions such as the internal APC adjustment, BIAS_APC (Auto “Ibias” Setting), LD Power Attenuation and Shading Correction with digital interface achieving with the internal arithmetic circuits.
