    filter cap parallel on feedback resistor for buck dc/dc question

    that makes sense. I suppose the cap should then be valued such as the impedance at the given vout voltage doesnt exceed the µC's voltage level. If i may ask a follow up question, when deriving transfer function, should it be done with respect to VOUT or with respect to the feedback node (node...

    filter cap parallel on feedback resistor for buck dc/dc question

    Looking at a TI application note they have placed the filter cap parallel to the resistor on the "high side" (see attached picture). the capacitor would create a low impedance path for high frequency and almost have no voltage drop, wouldnt the high frequency noise then be sampled at the...

    frequency of commutaion of bldc diy project

    Hello. I was creating a bldc driver using no bldc driver IC but with 3 mosfets half bridges. The embedded code was switching between the commutation stages, starting slow with an increasing frequency of steps using a timer ISR and moving its start value closer and closer to its max (255 bits)...
