Hi John,

Excellent work as usual, and very relevant to using modern displays such as OLEDs. All the ones I've encountered need some particular high voltage, so it is good to see the various boost converter implementations people use for them.

Great great work, [mention:f80b53cee57c44bc9d7c577d07d7c791:e9ed411860ed4f2ba0265705b8793d05] !!

The 40 volt part has a classic boost converter in it.

I've redrawn your schema a little bit to make that more apparent.

Here's the classic drawing (taken from Analysis of Four DC-DC Converters in Equilibrium )

Great debug description John.

I like your nice and steady approach to finding and fixing problems.

Well done.

Sounds very similar to how I was reverse engineering a schematic when none existed.

Many people would not think they could reverse engineer it, so well done for explaining it.
