These products apply to:
Continuous
1) Where the voltage of the input power supply
is fixed (voltage variation ≤ ±5%);
Free air convection
2) Where isolation is necessary between input
and output (isolation voltage ≤3000VDC);
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.
