IMX7 DC-DC Series Data Sheet
7-Watt DC-DC Converters
Thermal Considerations
If a converter, mounted on a PCB, is located in free, quasi-
stationary air (convection cooling) at the maximum ambient
temperature TA max (see table Temperature specifications) and
is operated at 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 depend on 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.
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. 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 limitation shuts down the converter, when a short
circuit is applied to the output. It acts self-protecting, and
automatically recovers after removal of the overload condition.

V). The cross-load effect is negligible.
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.
Connection in Series or Parallel
The outputs of single or double-output models can be
connected in series without any precautions, taking into
consideration that the output voltage should remain below 60 V
for SELV operation.
Both outputs of double-output models can be connected in
parallel without any precautions. Several converters (single- or
double-output models) with equal output voltage can be put 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.
