    Makita charger flyback controller identification

    Hi All,
    I have a Makita DC10WD charger (US version) that I opened up to figure out how to convert it to 230V (actually doesn't need any work except the mains plug )

    During the "reverse engineering" i tried to do I encountered a device with "funny" (custom?) marking - according to its connections it seems to be the flyback controller, its in a SOT23-6 (or similar) package and as you can see marked with a (rather unique according to my experience and web search) 72-63-22 marking.
    from measurement it is a 65kHz device.

    out of curiosity - does anyone have any idea what part this actually is?
    Thanks!

      ASUS X54H laptop thinks it's always charging even with charger unplugged
      by flat-earther
      The charging indicator light on my ASUS X54H laptop is always on even when the charger is disconnected.

      Windows also shows ''Plugged in'' when charger is not connected.

      This problem started year ago gradually, when unplugging the charger the charging light took several seconds to disappear, then minutes, and now almost always on even when unplugged for an entire day.
      Strangely, before sometimes immediately when plugging in the charger the charging light went away, and later came back with it connected.
      If I let battery run out and say it has 3% Windows will...

      Lenovo T460 Only Charges on One Charger
      by motormayhem
      Laptop Question
      Hello,
      I'm working on a Lenovo T460 that has been having trouble charging as of late. Its worked well since I've owned it for a few years. When I went to use it the other day it was dead and wouldn't turn on (was sitting on an Anker 65W GaN charger). After some fiddling with the charger I got it to turn on and start charging, but seemed like the charger was not working as it should (took a few plug and unplug cycles to get it to start charging).

      A day later it was dead again and wouldn't boot/charge no matter what I did. No lights or anything when...

      Xbox Series S/X controller Parts identification please
      by Techie_hobby1
      Hi, could someone please help me here to identify these blue SMD 0201 components.
      I also have a spare broken board (same model) and can confirm same components installed.
      Strangely though they have identified Z1 as the same component even though it differs from Z2 and Z3.
      It's from an Xbox Series S/X controller that I am attempting to fix for my Son..
      yes I hear a lot of people saying “Just buy a new one because they are cheap” buy this is the White PCB limited edition.

      Also identification for the other component EW=9L N13
      Thanks in advanced

      ISL88739AHRZ ISL88739 Laptop Battery Charger Datasheet
      by Document Archive
      The ISL88739 & ISL88739AHRZ are a highly versatile combo battery charger
      configurable for operating as either a Hybrid Power Boost (HPB)
      charger or a Narrow VDC (NVDC) charger, supporting 2-, 3-, or
      4-cell batteries. Both configurations allow the battery to work with
      the adapter together to supply the system load when it exceeds
      the adapter capability, referred to as system Turbo mode. HPB
      charger configuration reverse-boosts battery energy to the system
      bus to help the adapter provide the system power in Turbo mode.
      NVDC charger configuration...
