Thermal Considerations
If a converter, mounted on a PCB, is located in free, quasi-
stationary air (convection cooling) at the maximum ambient
temperature T A max (see table Temperature specifications)
and is operated at nominal input voltage and output power,
the case temperature T C measured at the measuring point of
case temperature T C (see Mechanical Data ) will approach the
indicated value T C max after the warm-up phase. However, the
relationship between T A and T C depends heavily on the
conditions of operation and integration into a system. The
4 Watt DC-DC Converters
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 and is only
recommended in applications, where one converter is able to
deliver the full load current, e.g., in true redundant systems.
Typical Performance Curves
V o [V]
thermal conditions depend on input voltage, output current,
airflow, temperature of surrounding components and surfaces
and the properties of the printed circuit board. T A max is
therefore only an indicative value, and under practical
operating conditions, the ambient temperature T A may be
higher or lower.
Caution: The case temperature T C measured at the measuring
point of case temperature T C (see Mechanical Data ) may under no
circumstances exceed the specified maximum. The installer must

limits stated in the table Temperature Specifications.

Short Circuit Behavior
The current limitation shuts down the converter, when a short
V o versus I o (typ) of single-output models (20IMX4-05)
circuit is applied to the output. It acts self-protecting, and
automatically recovers after removal of the overload condition.

Output Overvoltage Protection
The outputs are protected against overvoltages by Zener
diodes. In the event of an overvoltage, the converter 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 converters are not designed to withstand external
overvoltages applied to the outputs.
