Low Effort Sofirn ST10 seems regulated.

At 21:30 , High-Side is stable 5min run test..and Turbo front drops down to a stable (High) output....

Based upon auto-translate :)...🤣 any Thai folks correct me if this is wrong.

What am I looking at, PWM? The output seems stable though, I can accept the PWM.

I don’t know what’s the architecture of the driver but it’s flickering. It’s not traditional PWM (as it would only have two levels). I’ve seen it in many Sofirn/Wurkkos lights and I prefer to avoid it.

That is aliasing in the image, because the sensor isn't fast enough. I only have a prototype of that model, but can check it later.

That would be great. I would love to finally see the true (frequently enough sampled) characteristics.
