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 for
the PKY 2616 PI is 150 kHz.
Conducted EMI Input terminal value (typ)
EMI without filter @Vi=27 V, Io=Imax. External input capacitor: 220μF.
External filter (class B)
Required external input filter in order to meet class B in
EN 55022, CISPR 22 and FCC part 15J.
Filter components:
C1, C2, C3 = 5
μF
(100V, ceramic)
C4, C5 = 10nF
(2000V, ceramic)
C6 = 2x470
μF (100V,
electrolytic)
L1, L2 = 2.6mH

Test set-up
Layout recommendation
The radiated EMI performance of the DC/DC converter 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.
