Layout recommendations
The radiated EMI performance of the product will
depend on the PWB layout and ground layer design.
It is also important to consider the stand-off of the product.
If a ground layer is used, it should be connected to one of the
output terminals and the equipment ground or chassis.
A ground layer will increase the stray capacitance in the PWB
and improve the high frequency EMC performance.
Output ripple and noise
Output ripple and noise measured according to figure below.
See Design Note 022 for detailed information.
