The datasheet for the Rohm BD9890FV inverter controller states that "a
strong electromagnetic field may cause the IC to malfunction":

http://www.rohm.com/products/databoo...bd9890fv-e.pdf

However, the above warning may be a general one, as it occurs
alongside other general warnings including "mounting failures, such as
misdirection or miscounts, may harm the device".

What if you tried shielding the BD9890FV IC inside a metal box ???

Or what about a grounded metal plate above it, and a plate below it on
the underside of the PCB?
