TYPICAL CHARACTERISTICS

APPLICATION NOTE

Temperature Derating Graph

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.

Recommended Circuit

RECOMMENDED CIRCUIT

All the WRE_YD-4W&WRE_YD-4W Series have been tested according to

the following recommended testing circuit before leaving factory.This series

should be tested under load(See figure 1).

Output Graph

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

capacitance properly or choose capacitors with low ESR. 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).

General:

Cin: 5V＆12V 100μF

24V＆48V 100μF-47μF

Cout: 10μF/100mA

Input current

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

ripple voltage do not exceed indexes of the converter. Input current of

power supply should afford the startup current of this kind of DC/DC module

(See figure 2).

General:Ip≤1.4*Iin-max

No parallel connection or plug and play
