APPLICATION NOTE

1) Requirement on output load

In order to ensure the product operate efficiently and reliably, in addition to a max load

(namely full load), a minimum load is specified for this kind of DC/DC converter. Make sure

the specified range of input voltage is not exceeded, the minimum output load no less than

10% load. If the actual load is less than the specified minimum load, the output ripple may

increase sharply while its efficiency and reliability will reduce greatly. If the actual output

power is very small, please add an appropriate resistor as extra loading, or contact our

company for other lower output power products.

2) Recommended Circuit

All the WRD_(M)P-3W Series have been tested according to the following recommended

testing circuit before leaving factory. This series should be tested under load (see Figure 1).

If you want to further decrease the input/output ripple, you can increase capacitance

properly or choose capacitors with low ESR. However, the capacitance should not be too

high, or may cause start-up problem. If you want to use the products in high EMI, please

choose our metal packaged products (WRD_MP-3W). For every channel of output, provided

the safe and reliable operation is ensured, the greatest capacitance of its filter capacitor sees

(Table 1). General:

Cin: 5V,12V

Cout: 10μF/100mA

3) Input current

While using unstable power source, please ensure the output voltage and ripple voltage do

not exceed indexes of the converter. The preceding power source must be able to provide for

converter sufficient starting current Ip (Figure 2).

General: Ip ≤1.4*Iin-max

4) No parallel connection or plug and play

Note:

1. The load shouldn't be less than 10%, otherwise ripple will increase dramatically.

2. Operation under 10% load will not damage the converter; However, they may not meet all specification listed.

3. All specifications measured at Ta=25°C, humidity<75%, nominal input voltage and rated output load unless otherwise specified.

4. In this datasheet, all the test methods of indications are based on corporate standards.

5. Only typical models listed, other models may be different, please contact our technical person for more details.
