BQ501210 Wireless Power Transmitter EVM

We cannot guaranteed EMI compliance of a customer design with FCC or other emissions standard even if they are based on the EVM design.  Layout, form-factor, PCB, component selection are just some of the factor that will drive EMI performance. 

Areas that will generate switching noise and require during layout:

1.) Main output H-Bridge (EVM U2&U3) -- Switch nodes add place for snubber ckt on each node, keep high freq decoupling capacitors close to switch ckt and keep traces short.

2.) Rail Buck (EVM U1) -- Switch node add place for snubber ckt, keep V-in decoupling capacitors close.

3.) 19V to 3.3V Buck (EVM U5) -- Lowest power of the three but apply above to this ckt also.

4.) Input Power LInes -- Common Mode choke add place for additional filter capacitor.

5.) bq501210 IC (EVM U4) -- Internal HF clock, keep capacitors for Pin 44, 45, 46, 7 and 47 close to IC with good ground return back to IC.
