In this installment of Circuit VR, we’ll look at a simple ... boost-buck when you just can’t decide. We will flesh out the design more next time. We’ll eventually get to a buck converter ...

[Great Scott] should win an award for quickest explanation of a buck ... PWM on an Arduino, but a closer inspection with an oscilloscope still shows 5V peaks that would be dangerous to a 3.3V circuit.

Combining a buck-boost topology and Silent Switcher technology brings very low EMI at the highest power-conversion efficiency ...
