Over Voltage Protection (OVP)
The DC/DC converters have over voltage protection that will
shut down the DC/DC converter in over voltage conditions.
The DC/DC converter will make continuous attempts to start
up (non-latching mode) and resume normal operation
automatically after removal of the over voltage condition.
The output voltage depends on the input voltage. The internal
OVP circuit detects the input voltage and is activated at an
input voltage threshold between the maximum and absolute
maximum level.
Over Current Protection (OCP)
The DC/DC converters include current limiting circuitry for
protection at continuous overload.
The DC/DC converters will go into hiccup mode for output
currents in excess of max output current (max IO). The output
will go through repeated cycles of shut-down and restart with a
duty cycle of 7 ms on and 21 ms off. During the 7 ms on and a
load of 3 m the output current will reach approximately
190 A. The DC/DC converter will resume normal operation
after removal of the overload. The load distribution should be
designed for the maximum output short circuit current
specified.
