Connection for standard use :

Cin: External capacitor on the input side
Co: External capacitor on the output side

Reverse input voltage protection :

TAvoid the reverse input voltage because it will damage the power supply. Installing an external diode can protect the converter from the reverse input voltage.
 (Figure 6.1)

Series and parallel operation:

I. Series operation Most power converters can be operated in series if they have overload limitation by either constant current or constant power circuits. To protect each output from the reverse voltage applied by the other unit in the event of load short circuits, reverse biased diodes are used as shown in Figure 7.1
(Figure 7.1)

II. Parallel operation This is only recommended with power converters specifically designed for parallel connection. In the parallel redundant scheme illustrated in Figure 3.2 one of the power converters could be replaced by a battery followed by a DC-DC converter to provide a no-break power system in the event of main supply failure.

Peak-to-Peak Output Noise Measurement Test :

Use a Cout ceramic capacitor. Please refer to capacitor value of every series. Scope measurement should be made by using a BNC socket, measurement bandwidth is 0-20 MHz. Position the load between 50 mm and 75 mm from the DC-DC Converter.
