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.

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

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
