DESCRIPTION

The PWR13XX Series offers a broad line of low-cost,
high-isolation voltage, unregulated, single and dual output
DC/DC converters in a 24-pin DIP package. These small
converters offer a 4000V isolation rating in a 1.25" x 0.8"
package area.

The dielectric withstand characteristics of each converter
is tested in production to ensure barrier integrity. During the
development of the PWR13XX Series extensive testing
was done to verify that subjecting the barrier to as many
as ten barrier tests will not destroy the barrier.

The PWR13XX Series uses advanced circuit design and
packaging technology to realize superior reliability and
performance. A 220kHz driven push-pull oscillator is used
to ensure stable frequency and non-saturating operation
of the input stage. This means there are no high peak
voltages or currents like other design topologies, which

can reduce unit reliability. Reliability is further enhanced
by the use of MOSPOWER transistors. These rugged
devices permit higher frequency operation with less
complicated drive circuitry than is possible with bipolar
power transistors. Reduced parts count adds to the reliability
of the PWR13XX Series.

The high efficiency of the PWR13XX Series means less
internal power dissipation. With less heat to dissipate,
the PWR13XX Series can operate over a wider ambient
temperature range with no degradation of reliable operation.

The PWR13XX Series offers the user low cost without
sacrificing reliability. The use of surface mounted devices
and manufacturing technologies make it possible to offer
premium performance and low cost. Testing of the
PWR13XX isolation barrier is performed per the methods
set forth by UL544, VDE750, CSA 22.2 and IEC 601-1.
