Recommended Circuit All the WRB_YQD-30W 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 ON/OFF Control Pin CONTROL INPUT.....................................PIN4 CONTROL COMMON................................PIN2 LOGIC COMPATIBILITY......CMOS OR OPEN COLLECTOR TTL CONTROL VOLTAGE ON............+5.5VDC min OR OPEN CIRCUIT OFF......+2.5VDC max. OR SHORT TO PIN2 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).
