APPLICATIONS
The B_(X)T-1W 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.
