555 Tested feedback - 2

Constant voltage using a PWM (left) and (right) VCO pin 5 control. I wonder if this works in real life as a feedback for the first 555.

I still don't see where your coming from. Did you remember to include the user manual with this?

The pwm supplies the time of the pulse width, the VCO is watching the voltage drop due to the load and can increase the time or retard the timing due to the load to maintain control of set voltage while the current variable is load dependent. Say taking a battery from dead too full charge, load current variable on lead acid type. Dead battery gets lots of cycles per second at a set voltage and as the battery fills the c.p.s. drop too not overheat the cell's for a faster safe charge.

Same thing a couple of transistor can do, i have never seen this before, but as we know a 555 circuit can be used for any and everything.

I'm not sure you don't understand or you don't want to understand. The right 555 timer is only wasting energy, the frequency is only dependent to the left 555 timer. Even the load current does not make any significant change.
