APPLICATION NOTES

Requirement On Output Load

Output Voltage Regulation and Over-voltage

Protection Circuit

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.

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).

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).

Overload Protection

Under normal operating conditions, the output

circuit of these products has no protection against

overload. The simplest method is to connect

GND

self-recovery fuse in series at the input end or add a

circuit breaker to the circuit.

(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 recommended capacitance

of its filter capacitor sees (Table 1).

No parallel connection or plug and play.

Note:

1. All specifications measured at Ta=25°C, 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.
