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.

To ensure this module can operate efficiently
and reliably, During operation, the minimum output
load is not less than 10% of the full load, and that
this product should never be operated under
no load! If the actual output power is very small,
please connect a resistor with proper resistance at
the output end in parallel to increase the load.

If you want to further decrease the input/output
ripple, an “LC” filtering network may be connected
to the input and output ends of the DC/DC
converter, see (Figure 1).

It should also be noted that the inductance and
the frequency of the “LC” filtering network should
be staggered with the DC/DC frequency to avoid
mutual interference. However, the capacitance of
the output filter capacitor must be proper. If the
capacitance is too big, a startup problem might
arise. It’s not recommended to connect any
external capacitor in the application field.

a
linear voltage regulator with

Under normal operating conditions, the output
circuit of these products has no protection against
over-current and short-circuits. The simplest
method is to connect a self-recovery fuse in series
at the input end or add a circuit breaker to the
circuit.
