Hi,
I have query about recommend layout for DC DC converter. In pcb layout, what should be there below Switching node i.e. inner layers.? I have gone through TI recommend layout which has ground plane below Switch node.
Due to pcb constraints, Is it ok to leave empty/void i.e. no copper plane below SW node and inductor? Will it have bad results?
Thanks,
P B S Varma.
