requirements
CB0505XT-1W is specially designed for applications where an isolated voltage is required in a distributed power supply system. It is suitable
for
1.Where the voltage of the input power supply is stable (voltage variation: ±10%Vin);
2.Where isolation is necessary between input and output (isolation voltage ≤1000VDC);
3.Where do not has high requirement of line regulation, load regulation and the ripple & noise of the output voltage;
Such as: pure digital circuits, low frequency analog circuits and IGBT power device driving circuits.
