KHz Temperature Derating Graph RECOMMENDED CIRCUIT Output Graph operation instructions at Case material 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 WRA_ZMDP10&WRB_ZMDP10 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 : Output External Capacitor Table(Table 1) 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).

No parallel connection or plug and play. Use dual output simultaneously,forbid pening output pin (0V) to use as single output. 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.
