Recommended testing and application circuit

If

you want

to

further

decrease

the

input/output ripple, an

“

LC ” filtering network may be connected to

the

input

and

output

ends of the DC/DC converter, see (Figure 1).

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. 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 not recommend to connect any external capacitor in the

application field with less than 0.5 watt output.

Output Voltage Regulation and Over-voltage Protection Circuit

The simplest device for output voltage regulation, over-voltage and

over-current protection is a linear voltage regulator with overheat

protection that is connected to the input or output end in series (Figure 2).

Dual Output

Overload Protection

Under normal operating conditions, the output circuit of

these products has no protection against overload. The simplest

method is to connect a self-recovery fuse in series at the input

end or add a circuit breaker to the circuit.

No parallel connection or plug and play

Note:

1. All specifications measured at Ta=25, humidity<75%,nominal input

voltage and rated output load unless otherwise specified.

2. Only typical models listed, other models may be different,

please contact our technical person for more details.

3. Operation under minimum load will not damage the

converter; However, they may not meet all specification listed.
