APPLICATIONS
The B_S-W2/B_D-W2 Series are specially
designed for applications where a group of polar
power supplies are isolated from the input power
supply in a distributed power supply system on a
circuit board.
These products apply to:
1) Where the voltage of the input power supply
is fixed (voltage variation ≤ ±10%);
2) Where 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.
