SoundMagus X3500 output driver IC

[Maxikill97]

Hi there guys,

Does anybody know the replacement IC for the output PWM of this driver board?

In an other post I saw this IC could be a 45ccdkk. Which I can't get from my suppliers and seems to be a pretty unknown IC according to google.
Does anybody has a good alternative or know the correct IC type?

This is the output PWM which is going to the optocoupler board.
I changed all the drive transistors between the Optocoupler board and the PWM driver board. The components on the pwm driver board read normal. So I suspect the IC to be defect.

From a different amp.

That brown fixative on the bottom of the board needs to be completely removed from the amp. It becomes both conductive and corrosive and can cause all sorts of problems.

Thank you very much. I will order these soon.
