Description

The AK2550 is a one-channel anode common LDD (Laser Diode Driver) suitable for MFP (Multi Function Printer) and LBP (Laser Beam Printer).
The AK2550 has a built-in LDD that switches the LD (Laser Diode) current and a feedback type APC (Auto Power Control) circuit that keeps the LD light intensity constant while referring to the monitor PD (Photo Diode) current.
The AK2550 is applicable to systems where the power supply voltage is 3.3V ± 5% or 5.0V ± 5%.

Key Features

  • Auto Power Control circuit. | It is equipped with a feedback type APC (Auto Power Control) circuit that keeps the LD light intensity constant.

Applications

  •                                 Multi Function Printer, Laser Beam Printer, etc.
