Hello,
I have a first draft of a 24VIN 200VOUT PCB and I would appreciate any feedback and suggestions, especially from anyone who has experience with switching power supply design. This is a two-layer board with a ground plane on the bottom layer.
Some things that I considered while laying out the board are:
I have attached photos of the schematic and PCB Layers.
Thanks in advance.

Some things that I considered while laying out the board are:
- Creepage and clearance
- Minimizing area of switching loops
- Keeping input and output current loops flowing in the same direction
- Short traces
- No ground plane past transformer
- No ground plane under Rvout and Rdcm nodes to reduce capacitance
- Keep feedback trace far from transformer
I have attached photos of the schematic and PCB Layers.
Thanks in advance.
