DESCRIPTION

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.

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 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. 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 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 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.
