10. OUTPUT OCP AND SHORT-CIRCUIT PROTECTION
Output overload and short circuit conditional will cause the output voltage to decline or shutdown altogether.
is not over 85°C, the output recovers automatically when the short or OCP conditions are removed. In the case of slight overloading,
the output voltage may not shut down, but the converter may build up heat over time, causing over-temperature shutdown.
11. OVER-TEMPERATURE PROTECTION
When the case temperature reaches about 85°C, the converter's built-in protection circuit will shut down the output. When the
temperature is reduced enough to a safe operating level, the converter will recover to normal operations automatically.
12. OUTPUT OVP
In case the output voltage exceeds the OVP threshold, the converter shuts down.
13. OUTPUT PARALLEL CONNECTIONS
The converter is not designed for load share on the output. One may be inclined to use this circuit to force current sharing by
trimming the output voltages for each converter. However, this circuit me not reliably or accurately divide the load current, as the
device characteristics of the converters or the diodes may not be balanced over a range of operating conditions. We generally do not
recommend this circuit to increase power output over a single converter. Instead, we recommend this setup for redundancy only,
having one converter as a backup in case of a failure. Make sure the OR-ing diodes can handle the voltage and full load current.
