I am trying to identify this component, I need to replace it. It is in a Belkin SoundForm Elite that keeps rebooting.
The plug-in charger is 19V.
The component is the eight-legged one marked 0U=V2P (removed in second picture).

That's no microcontroller. Based on things surrounding it, it's a buck regulator.
In fact, it's a Richtek RT6217A.
Datasheet confirms that RT6217AHGJ8F in TSOT-23-8 package has product code "0U=", and the pinout matches too. In addition to the triangular mark for pin 1.
Also, if you think replacing the regulator fixes it, it might not if the problem is elsewhere and regulator is either controlled incorrectly or it shuts down due to overcurrent protection. So don't replace it unless you know it is broken, most likely it isn't if you are just guessing instead of doing proper fault analysis.
