This training series covers a number of common mistakes in point-of-load
DC/DC converter design and testing. In this video, we will review the buck
converter and explore considerations for converter capabilities and part
selection in DC/DC designs.

Thanks for excellent video! However, there is a small correction to be made @10:21. The thermal picture does not show junction temperature but case temperature. So you first need to delta between junction and case before making this conclusions. Thanks anyhow, I learned a lot!

As a hobbyist I want to use TI's 'Simple Switcher' DC-DC modules to build power supplies for 12V to 170V (Nixie tubes) and 12V to 25 Volt (VFD tubes). But I get lost in the welth of choice... Is it possible to give me a hint which 'Simpel Switcher' module(s) to use please? Thank you very much!

what is the best condition of DC-DC boost converter to rest in high output?

What is your Vsw ??? is it taken across Q1 or Q2??? Not mentioned clearly.... But as far as the graphs you have given in bottom left corner it is across Q2...

Can we operate DC DC converter without feedback.

@edinfific2576 3 жыл бұрын

Of course you can, but your voltage will vary greatly.

What do the arrows indicate ? Far more understandable IF the Q2 arrows were reversed ; then the arrows would properly indicate CURRENT flow : of course Q1 conducts first , Q2 conducts AFTER Q1

@RainLovesCobain Жыл бұрын

I think the arrow indication is still correct. You can't change the direction of the flowing current through an inductor instantly, so even when Q1 is not conducting, the current flows in the same direction as before, thus the load is still getting supplied. You can also check the Q2 switch in its diode form. Then you will see that the current flow direction must be this way.

Isn't 1.2 MHz actually 830 ns, and not the 83 ns in the vid?

@RainLovesCobain Жыл бұрын

no, if you use a calculator the result will be shown as 8.33x10^-8 which is basically 83 ns

Chicken and egg. I wish just one of these electronic people would at least acknowledge the existence of independent and dependant variables, and NO, you can't switch them to fit your analogy. Just say what causes what instead of all this double talk.
