EMC Specifications
The PKS DC/DC power module is mounted on a double sided
printed circuit board (PB) with groundplane during EMC
measurements.
The fundamental switching frequency is 850 kHz ± 10% in
PKS 2111 and 650 kHz ±10% in PKS 2113 and PKS 2115
@ IO=IOmax.
Conducted EMI (input terminals)
Operating information
Input and Output Impedance
Both the source impedance of the power feeding and the load
impedance will interact with the impedance of the DC/DC power
module.
It is most important to have the ratio between L and C as low as
possible, i.e. a low characteristic impedance, both at the input and
output, as the power modules have a low energy storage capability.
A capacitive compensation is necessary if the source or load induc-
tance is larger than 10
mH. Use wet electrolytic capacitors.
Their equivalent series resistance together with the capacitance acts
as a lossless damping filter. Suitable capacitor values are in the range
10–100
mF. Tantalum capacitors are not suitable due to their low
ESR value.

Undervoltage lockout
The PKS 2000 series is designed to operate over an input voltage
range of 18 to 36 V dc. If the rise time of the input voltage source is
very slow, a few hundred milliseconds for instance, the power
modules will draw excessive current during start-up as long as the
source voltage is less than the minimum rated voltage. In these
situations, an undervoltage lockout circuit can be added as shown in
fig. 5.
Over Voltage Protection (OVP)
The remote control can be utilized also for OVP by using the
external circuitry in fig. 4. Resistor values are for 5 V output
applications, but can easily be adjusted for other output voltages and
the desired OVP level.
Remote Control (RC)
Turn-on or turn-off can be realized by using the RC-pin. Normal
operation is achieved if pin 1 is open (NC). If pin 1 is connected to
pin 2 the PKS DC/DC power module turns off. To ensure safe turn-
off the voltage difference between pin 1 and 2 shall be less than
0.8 V. RC is TTL open collector compatible (see fig. 3). Pin 1 is an
output and no current should be driven into pin 1. Use a diode if
necessary e.g. totem pole TTL logic. The internal pull-up resistance
is 10 k
W to a 2.5V reference voltage.
