PRODUCT OVERVIEW
The PWR13XXC 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.
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 PWR13XXC Series.
The dielectric withstand characteristics of
each converter is tested in production to ensure
barrier integrity. During the development of the
PWR13XXC Series extensive testing was done
to verify that subjecting the barrier to as many
as ten barrier tests will not destroy the barrier.
The high efficiency of the PWR13XXC Series
means less internal power dissipation. With
less heat to dissipate, the PWR13XXC Series
can operate over a wider ambient temperature
range with no degradation of reliable operation.
The PWR13XXC 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.
The PWR13XXC 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
PWR13XXC isolation barrier is performed per
the methods set forth by UL544, VDE750, CSA
22.2 and IEC 601-1.
