Is there a good topology for splitting a DC power supply from a few LM2576 and LM2577?

So, this isn't the most serious project, more of a toy/hack, but I have a some LM2576 and LM2577 and I wanted to see if I could somehow get an adjustable dual rail (bipolar) supply out of them, for ...

Is it possible to get a high efficiency buck-boost converter by switching between the two?

Many buck-boost converters work by boosting to an intermediate voltage, then bucking to the desired voltage. What if instead, it had a separate buck and boost section in parallel, and switched between ...

Why overshoot happens in Inductor voltage in an open loop DC-DC buck converter?

I am extremely confused about why this overshoot occurs in the Inductor voltage waveform in buck converter and also why the time to achieve steady state reduces on increasing the load resistance. ...
