DESCRIPTION

The PWR70XXAC Series uses advanced circuit design

and packaging technology to realize superior reliability and

performance. A 170kHz 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 severely

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 PWR70XXAC Series.

Continuous short-circuit protection and foldback current limiting

make the PWR70XXAC Series rugged devices for use in

demanding system applications. These features add to the

overall reliability of the PWR70XXAC Series by reducing the

possibility of inadvertently damaging the unit due to an output

overload.

The high efficiency of the PWR70XXAC Series means low

internal power dissipation. With less heat dissipated, the

PWR70XXAC Series can operate at higher ambient temperature

with no degradation of reliablility.

The PWR70XXAC Series offers the user low cost without

sacrificing reliability. The use of surface mounted devices and

manufacturing technologies makes it possible to offer premium

performance and low cost.
