Filtering

To get an extreme low ripple,an "LC"filtering network

may be connected to the input and output ends of the

DC/DC converter.Which may produce a more significant

filtering effect.It should also be noted that the inductance

and the frequency of the "LC"filtering network should be

staggered with the DC/DC frequency to avoid mutual

interference see (Figure 1).

In some circuits which are sensitive to noise and ripple.a

filtering capacitor may be added to the DC/DC output

end and input end to reduce the noise and ripple.

However, the capacitance of the output 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 greatest capacitance of its filter capacitor sees

(Table 1).

It's not recommend to connect any external capacitor in

the application field with less than 0.5 watt output.

Overload Protection

Under normal operating conditions, the output circuit

of these products has no protection against over-current

and short-circuits.The simplest method is to connect a

self-recovery fuse in series at the input end or add a

circuit breaker to the circuit.

When the environment temperature is higher than

71℃, the product output power should be less then

60% of the rated power.

No parallel connection or plug and play.

Use dual output simultaneously, forbid opening

output pin (0V) to use as single output.

Requirement on output load

To ensure this module can operate efficiently and reliably, a minimum load is specified for this kind of

DC/DC converter in addition to a maximum load(namely full load).During operation, make sure the

specified range of input voltage is not exceeded,the minimum output load is not less than 10% of the full

load, and that this product should never be operated under no load!
