PKL 4316 Series
EN/LZT 146 039 R1A Ericsson Power Modules, November 2003
Operating Information
Input Voltage
The input voltage range 36…75Vdc meets the requirements
of the European Telecom Standard ETS 300 132-2 for normal
input voltage range in –48V and –60V DC systems, -40.5…-
57.0V and –50.0…-72V respectively. At input voltages
exceeding 75V, the power loss will be higher than at normal
input voltage and TPcb must be limited to absolute max
+125
°C. The absolute maximum continuous input voltage
is 80Vdc.
Turn-Off Input Voltage
The PKL 4316 Series DC/DC converters monitor the input
voltage and will turn on and turn off at predetermined levels.
The minimum hysteresis between turn on and turn off input
voltage is 1V where the turn on input voltage is the highest.
Output Voltage Adjust (Vadj)
All PKL 4316 Series DC/DC converters have an Output
Voltage adjust pin (Vadj). This pin can be used to adjust the
output voltage above or below Output voltage initial setting.
When increasing the output voltage, the voltage at the output
pins (including any remote sense offset) must be kept below
the overvoltage trip point, to prevent the converter from
shut down. Also note that at increased output voltages the
maximum power rating of the converter remains the same, and
the output current capability will decrease correspondingly. To
decrease the output voltage the resistor should be connected
between Vadj pin and –Sense pin. To increase the voltage the
resistor should be connected between Vadj pin and +Sense
pin. The resistor value of the Output voltage adjust function is
according to information given under the output section.
Remote Control (RC)
The PKL 4316 Series DC/DC converters have remote control
function referenced to the primary side (minus input), with
negative and positive logic options available. The RC function
is CMOS open drain compatible. Maximum sink current is
1mA. When the RC pin is left open, the voltage generated
on the RC pin by the DC/DC converter is 3.5-6.0V. The
maximum allowable leakage current of the switch is 50A.
The standard converter is provided with “negative logic”
remote control and will be off until the RC pin is connected to
the minus input. To turn on the converter the voltage between
RC pin and minus input should be less than 1V. To turn off
the converter the RC pin should be left open, or connected
to a voltage higher than 4V referenced to minus input. In
situations where it is desired to have the converter power up
automatically without the need for control signals or a switch,
the RC pin can be wired directly to the –Input circuit on the
application board.
The second option is “positive logic” remote control, which
can be ordered by adding the sufx “P” to the end of the
part number. The converter will turn on if the input voltage
is applied with the RC pin open. Turn off is achieved by
connecting the RC pin to the minus input. To ensure safe turn
off the voltage difference between minus input pin and the RC
pin shall be less than 1V. The converter will restart when this
connection is opened.
All PKL 4316 Series DC/DC converters have remote sense that
can be used to compensate for moderate amounts of resistance
in the distribution system and allow for voltage regulation at
the load or other selected point. The remote sense lines will
carry very little current and do not need a large cross sectional
area. However, the sense lines on the PCB should be located
close to a ground trace or ground plane. In a discrete wiring
situation, the use of twisted pair wires or other technique to
reduce noise susceptibility is highly recommended. The remote
sense circuitry will compensate for up to 10% voltage drop
between the sense voltage and the voltage at the output pins.
The output voltage and the remote sense voltage offset must be
less than the minimum over voltage trip point. If the remote
sense is not needed the –Sense should be connected to –Out and
+Sense should be connected to +Out.
