APPLICATION NOTE
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 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 the external capacitor table. To get
an extremely 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).
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! 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.
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.
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 (see Figure 2).
