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 ...

Idea behind current mode control in DC-DC converter
I am learning about control strategies for DC-DC converters.
While I find voltage mode control easy to understand, I struggle to understand
current mode control.
Is the idea here to control the ...

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.
