Dear forum colleagues,
Here I have a Pioneer - AVH-z5200dab of which the 5Vdc USB voltage is missing.
IC451 is defective and a capacitor is defective (short circuit).
Now I can't find a service manual for this specific unit anywhere, nor can I identify the step-down converter chip IC451.
This is (I think) a Microchip(?) DC/DC converter in a QFN-24 package. I can't find the type on the Microchip site. It also does not work via Google and image search.
Markings on the chip: "008 630B"
Does anyone have an idea?
Input of this chip is the battery voltage of the car (12 to 14 Vdc) and the output (via a Coil) is 5Vdc for the USB connection.
Please let me know if anyone has an idea or needs more information,
Thanks in advance!
