These products apply to: 1) W here the voltage of the input power supply is fixed (voltage variation ≤ ±10%); 2) W here isolation is necessary between input and output (isolation voltage ≤1000VDC); 3) Where the regulation of the output voltage and the output ripple noise are not demanding. Such as: purely digital circuits, ordinary low frequency analog circuits, and IGBT power device driving circuits.
