If the total required output power is less than 10%, a parallel bleeding resistor is required, ensuring that the sum of the power consumption is always maintained at 10% minimum. 2) Recommended circuit for Ripple Reduction Input and/or output ripple can be further reduced by connecting "LC" filters to the input and/or output terminals of the DC-DC converter as shown in Figure 1.

Also, the capacitance of the output filter capacitor must be properly selected. If the capacitor value that is too high, the converter may not be able to properly start up. To ensured safe and reliable operation, the specified filter capacitor value in Table 1 must not be exceeded.

The best approach for protection the device is to add a self-recovery fuse or a circuit breaker in series to the input. 4)Input Over-voltage Protection Circuit For input overvoltage protection, simply use a linear voltage regulator with overtemperature protection in front of the DC-DC converter as shown in Figure 2. Vin GND REG +Vo DC DC 0V Figure 2 5) The total output power of the device has to be reduced to 60% or less of the rated output power at ambient temperatures above 71C. 6) These products are not hot-swappable and do not support parallel connection of their outputs. We recommended the use of a converter with higher output power capability to cover applications with higher power requirements. Note: 1.
