APPLICATIONS
The B0505YS-1W is specially designed for
applications where a single power supply is
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 and noise are not
demanding.
Such as: purely digital circuits, ordinary low
frequency analog circuits and IGBT power
device driven circuits, etc.
