MC33063 -- 9V to 5V
Custom -- 9V to 5V with the uni-polar or basically the ON-OFF control
. . . the uni-polar to bi-polar PWM control signal formation block (essential tests)
!! update !!
Random feedback circuitry . . . is "doable" test ::
The bi-polar control circuit -- occasionally skips to 800kHz mode::
With modified MOS-Fet drive stage -- without feedback stays at 166kHz
