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
305 kHz for PKR 4110B SI @ 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.
Filter components:
C1= 1μF 100V
C2= 10μF 100V
C3,C4= 2.2nF
1500Vdc
L1= Pulse PO354
1.17mH

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.
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.
