Thanks for your reply,so you suggest that all regulator should have 27V input.So which is better option for 5V volt regulator, 12V input from previous regulator or 27V individual supply??and which is more efficient??
Thanks for your reply,actually what i think is, if the regulator which gives 5v output,its better to give it 12v input rather 27v input for achieving better efficiency and wasting much less power.please suggest what should i do??
can i connect lm2576 in series ?? I have 27 volt supply,i need 24V,12V and 5V output..so can i connect 3 lm2576 in series like 1st one gives me 24v, which feeds 2nd lm2576 and gives me 12V and so on...
