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).

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.

The simplest device for input over-voltage protection is

a linear voltage regulator with overheat protection that is

connected to the input end in series(Figure 2).
