Full-Bridge SMPS on double sided PCB?

[grizedale]

Hello,

Is it recomended to do a full-bridge SMPS (330W; Vion = 90-265VAC) with charge-pump high-side gate drivers on a double -sided PCB?

eg using two NCP5181 gate driver IC's.......

..its just that its four gate drive signals to route....and i wonder if this makes some go to 4 layer PCB?

it would depend upon on overall size of PCB, I think if you are able to route (with necessary shielding or physical separation) i think 2 layer be OK.

convert the pcb to single sided
double layer pcb's are horrible from servicing point of view,
i have not been able to remove a SMPS transformer from a double sided board as yet

I think if you can separate between High voltage and low voltage for noise and other and shielding , thats very good to design multi-layer board as atripathi said.
