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.

Output Voltage
*Input voltage can’t exceed this value, or will cause the permanent damage.
Note: The load shouldn't be less than 10%, otherwise ripple will increase dramatically.
Operation under 10% load will not damage the converter; However, they may not meet all specification listed.
