Parallel and Series Connection
Outputs of equal nominal voltage may be parallel-connected.
Interconnect the current sharing pins T (pin 22) for even
distribution of the output current; see Auxiliary Functions .
Output Protection
A voltage suppressor diode, which in worst case conditions
fails into a short-circuit, protects the output against an
internally generated overvoltage. Such an overvoltage could
occur due to a failure of either the control circuit or the
switching transistor. The output protection is not designed to
withstand externally applied overvoltages.
Current Limitation
A constant current limitation circuit holds the output current I o
almost constant in the area of 100 to 120% of I o nom , when an
overload or a short-circuit is applied to the output. It acts self-
protecting and recovers – in contrary to the fold back method –
automatically after removal of the overload or short-circuit
condition.
Outputs can be series-connected with any other regulator,
provided that the regulators are powered by electrically
isolated source voltages. In series connection the maximum
output current is limited by the lowest current limitation.
