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

OUTLINE DIMENSIONS & FOOTPRINT DETAILS  
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
