EMC Specification
Conducted EMI measured according to EN55022, CISPR 22
and FCC part 15J (see test set-up). See Design Note 009 for
detailed information. The fundamental switching frequency is
180 kHz for PKB 4204B PI @ VI = 53 V, max IO.
Conducted EMI Input terminal value (typ)
EMI without filter
External filter (class B)
Required external input filter in order to meet class B in
EN 55022, CISPR 22 and FCC part 15J.
Components:
C1,2,3 = 1 F
(100 V, ceramic)
C4,5 = 2.2 nF
(2 kV, ceramic)
C6 = 220 F
(100 V, electrolytic)
L1,2 = 809 H
(common mode)
EMI with filter
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 DC/DC
converter.
If a ground layer is used, it should be connected to the output
of the DC/DC converter 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.
