APPLICATIONS
The A_(X)T-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:
Note: The A_XT-W2 series have no 3,6,8,9 pin. For example A0505XT-W2.
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.
