TYPICAL CHARACTERISTICS

Temperature Derating Graph

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).

(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

proper. If the capacitance is too big, a startup

problem might arise. For every channel of

output, providing the safe and reliable

operation is ensured, the greatest

capacitance of its filter capacitor refer to the

external capacitor table (table1).

APPLICATION NOTE

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, that this product should never be

operated under no load!

Overload Protection

Under normal operating conditions, the

output circuit of these products has no

protection against over-current. 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°C, 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.
