EMC Specification
Conducted EMI measured according to EN55022, CISPR 22
and FCC part 15J (see test set-up). See Design Note 009 for
further information. The fundamental switching frequency is
285 kHz for PKU 5310E PI, PKU 5311E PI, and PKU 5313E
PI. For PKU 5315E PI it is 315 kHz.

Layout recommendations
The radiated EMI performance of the Product will depend on
the PCB 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 the output of the product and the
equipment ground or chassis.
A ground layer will increase the stray capacitance in the PCB
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.
