5333h 1xha - CPS533 Voltage Regulator Info or Substitute

[Hundleton1]

Hi everyone, I hope it’s ok to post this here, if not I apologise and please tell me where would be best .


I am trying to find any info on a voltage regulator that’s labelled 5333h 1xha that we believe is a CPS533 5v regulator.

I can find nothing on this part at all. Not even a data sheet.

If anyone has any data sheets, info on supply or an alternative I and the FPV community would massively appreciate it .

I found a reference to CPS5333 in this teardown:

The part marking is 5333, not 5333H.

There is also a CPS8100GQ part in the same teardown. Its logo belongs to Convenient Power Semiconductor, also known as Convenient Power Systems.

Their web site is basically useless:

I did find a totally unrelated datasheet which confirms the identity of the company and logo:

Here is another reference to a CPS5333 buck converter:

I'm getting closer:
