Requirement On Output Load

To ensure this module can operate efficiently

and reliably, a minimum load is specified for this

kind

DC/DC converter

addition

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! 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 (IF_S(D)

–W25 Series).

Filtering

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

(Table 1).

’s not recommended to connect any external capacitor

in the application field with less than 0.5 watt output.

To get an extrem ely 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 (Figure 1).

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

°C, the product output power should

be less then 60% of the rated power.

No parallel connection or plug and play.
