DESIGN CONSIDERATIONS

1) Requirement on output load

To ensure this module can operate efficiently and reliably, During operation, the minimum output load is not less than 5% of the full load. If the

actual output power is very small, please connect a resistor with proper resistance at the output end in parallel to increase the load, or use our

company

’s products with a lower rated output power.

2) Overload Protection

Under normal operating conditions, the output circuit of these products has no protection against overload. The simplest method is to adda

circuit breaker to the circuit.

3) Recommended Circuit

If you want to further decrease the input/output ripple, a capacitor filtering network may be connected to the input and output ends of the DC/DC

converter, see (Figure 2).

It should also be noted that the capacitance of filter capacitor must be proper. If the capacitance is too big, a startup problem might arise. For

every channel of output, provided the safe and reliable operation is ensured, the recommended capacitance of its filter capacitor sees (Figure 2).

It

’s not recommended to connect any external capacitor in the application field with less than 0.5 watt output.

4)The input and the output of the product are recommended to be connected to ceramic capacitor or electrolytic capacitor.

Using tantalum capacitor may cause risk of failure

5) Cannot use in parallel and hot swap
