Is it advised to use the below power supply topology for a PCB design?
I have a input 12V supply and the board needs 5V(.5 A),3.3V(.4A),1.8V(2A) supplies.
12 V to 5 V (using Buck Regulator)
5V (Buck Regulator output ) to 1.8 V Buck Regulator/3.3 V LDO.{5 V to lower voltage conversion using switching regulators)
Is it advised to use the output from a buck regulator(5V) and use them to generate other lower voltages(using buck regulators)?
Will there be any issues w.r.to noise coupling or any other issues.Please advise.
