Operating information
Input Voltage
The input voltage range 18 to 72Vdc meets the requirements
of the European Telecom Standard ETS 300 132-2 for normal
input voltage range in –48 and –60 Vdc systems, -40.5 to -
57.0 V and –50.0 to -72 V respectively.
At input voltages exceeding 72 V, the power loss will be higher
than at normal input voltage. Precaution must be taken to
keep TP1 below +95°C. The absolute maximum continuous
input voltage is 80 Vdc.
Turn-off Input Voltage
The products 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. The input voltage supply must have low
impedance to prevent the risk of input oscillation, poor supply
can also cause shutdown-bouncing.
Remote Control (RC)
The products are fitted with a
remote control function referenced
to the primary negative input
connection (-In), with negative and
positive logic options available. The
RC function allows the product to
be turned on/off by an external
device like a semiconductor or
mechanical switch. The RC pin has
an internal pull up resistor to +In.
The maximum required sink current is 1 mA. When the RC pin
is left open, the voltage generated on the RC pin is
4.5 – 5.5 V.
The standard product is provided with “negative logic” remote
control and will be off until the RC pin is connected to the -In.
To turn on the product the voltage between RC pin and -In
should be less than 1V.
To turn off the converter the RC pin should be left open, or
connected to a voltage higher than 4 V referenced to -In. In
situations where it is desired to have the product to power up
automatically without the need for control signals or a switch,
the RC pin can be wired directly to -In.
The second option is “positive logic” remote control, which can
be ordered by adding the suffix “P” to the end of the part
number.
When the RC pin is left open, the product starts up
automatically when the input voltage is applied.
Turn off is achieved by connecting the RC pin to the -In. To
ensure safe turn off the voltage difference between RC pin
and the -In pin shall be less than 1V. The product will restart
automatically when this connection is opened.
See Design Note 021 for detailed information.
Input and Output Impedance
The impedance of both the input source and the load will
interact with the impedance of the DC/DC converter. It is
important that the input source has low characteristic
impedance.
The performance in some applications can be enhanced by
addition of external capacitance as described in External
Decoupling Capacitors.
If the input voltage source contains significant inductance, the
addition of a low ESR 47 F capacitor across the input of the
converter will ensure stable operation in all conditions.
External Decoupling Capacitors
The products have been designed to operate with a minimum
capacitance connected to their output.
When powering loads with significant dynamic current
requirements, the voltage regulation at the point of load can
be improved by addition of decoupling capacitors at the load.
The most effective technique is to locate low ESR ceramic and
electrolytic capacitors as close to the load as possible, using
several parallel capacitors to lower the effective ESR. The
ceramic capacitors will handle high-frequency dynamic load
changes while the electrolytic capacitors are used to handle
low frequency dynamic load changes. Ceramic capacitors will
also reduce any high frequency noise at the load.
It is equally important to use low resistance and low
inductance PCB layouts and cabling. If significant inductance
are within the load distribution, >50% of the stated “Minimum
Output Capacitance” shall be located at the module’s output.
External decoupling capacitors will become part of the control
loop of the DC/DC converter and may affect the stability
margins. As a “rule of thumb”, 100 F/A of output current can
be added without any additional analysis. The ESR of the
capacitors is a very important parameter. Ericsson Power
Modules guarantee stable operation with a verified ESR value
of >10 m across the output connections.
