IMX4 DC-DC Series Data Sheet
4-Watt DC-DC Converters
Thermal Considerations
If a converter, mounted on a PCB, is located in free, quasi-
stationary air (convection cooling) at the indicated maximum
ambient
temperature
TA max
(see
table:
Temperature
specifications) and is operated at its nominal input voltage and
output power, the case temperature
TC measured at the:
Measuring point of case temperature TC (see: Mechanical Data)
will approach the indicated value
TC max after the warm-up phase.
However, the relationship between
TA and TC depends heavily on
the conditions of operation and integration into a system. The
thermal conditions are influenced by input voltage, output
current, airflow, temperature of surrounding components and
surfaces and the properties of the printed circuit board.
TA max is
therefore only an indicative value and under practical operating
conditions, the ambient temperature
TA may be higher or lower
than this value.
Caution: The case temperature
TC measured at the Measuring
point of case temperature TC (see: Mechanical Data) may under
no circumstances exceed the specified maximum value. The
installer must ensure that under all operating conditions
TC
remains within the limits stated in the table:
Temperature
specifications.
Short Circuit Behavior
The current limit characteristic shuts down the converter whenever
a short circuit is applied to its output. It acts self-protecting and
automatically recovers after removal of the overload condition.
Output Overvoltage Protection
The outputs of the IMX4 converters are protected against
overvoltages by Zener diodes. In the event of an overvoltage
on the output, the unit will shut-down and attempt to restart
automatically. The main purpose of this feature is to protect
against possible overvoltages which could occur due to a
failure in the feedback control circuit. The units are not
designed to withstand external overvoltages applied to the
outputs.
Connection in Series
The outputs of single or dual output units can be connected in
series without any precautions, taking into consideration that
the highest output voltage should remain below 60 V for SELV
operation.
Connection in Parallel
Several
converters
with
equal
output
voltage
can
be
connected in parallel and will share their output current quite
equally. However, this may cause start-up problems at initial
start-up, and is only recommended in applications where one
converter is able to deliver the full load current, e.g, in true
redundant systems.
