Pioneer - AVH-z5200dab component identification

[dutn]

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!

Thank you lotas for the very fast reply! Pinout (Vinput, ground) looks correct to me.

Everything is correct here, it's from the service manual.

Good to know that the schematic comes from the service manual. Then I have enough information to carry out the repair. Thanks again, much appreciated! (I've been searching for the wrong manufacturer for days)
