These products apply to:
1) Where the voltage of the input power supply
is wide range (voltage range≤ 2:1);
2) Where isolation is necessary between input
and output(isolation voltage≤1500VDC);
3) Where the regulation of the output voltage
and the output ripple noise are demanded.

Note:
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:
1. All specifications measured at TA=25°C, humidity<75%, nominal input voltage and rated output load unless
otherwise specified.
2. Test ripple and noise by “parallel cable” method. See detailed operation instructions at Testing of Power
Converter section, application notes.
3. Operation under 10% load will not damage the converter; However, they may not meet all specification listed.
4. See below recommended circuits for more details.

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
