APPLICATION

NOTE

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

All the 10A_ZMD&10B_ZMD 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 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: 10μF-47μF

Cout: 10μF/100mA

CTRL Terminal

When open or high impedance,the converter work well; When this pin is

‘high’; the converter shutdown; It should be note that the input current (Ic)

should between 5-10mA, exceeding the maximum 20mA will cause

permanence damage to the converter.

The value of R Can be derived as follows :

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≤1.6*Iin-max

No parallel connection or plug and play
