Want to ask the great spirit when DC - DC module PCB layout FB foot reference voltage from the output stage which is better? Inductor or capacitor after?

CodePudding user response:

, of course, is the final output of electricity of subsection pressure value,

LZ of inductance and capacitance is not attached to? After the inductance or capacitance has any difference?

CodePudding user response:

reference 1/f, worldy response:

LZ of inductance and capacitance is not attached to? After the inductance or capacitance has any difference?

I design, before the review some questions: if the reference voltage on the capacitor after, capacitance filtering to a certain extent, and the time delay, take some clutter filter, chip itself cannot achieve the purpose of timely feedback, mainly is this

CodePudding user response:

Then all try bai, fairy may be able to detect the difference between

CodePudding user response:

That's all try bai, fairy may be able to detect the difference

CodePudding user response:

Should be in the end, that is, the power supply end of the load, fb is used to detect the load voltage, to maintain a constant, and the ripple of the filter is not eliminated by this principle to
You to see the giant DCDC data manual, there are reference PCB layout, to know,

CodePudding user response:

refer to fifth floor white no reply:

should be in the end, the load of the power supply side, fb is used to detect the load voltage, to maintain a constant, and the ripple of the filter is not eliminated by this principle to
You look at the giant DCDC data manual, there are reference PCB layout, will know that

thank you

also consult a great god, ripple filter is not eliminated by this way? This sentence is not very understanding, please advise
