DESCRIPTION
The PWR70XX 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 PWR70XX Series.
Continuous short-circuit protection and foldback current
limiting make the PWR70XX Series rugged devices for use
in demanding system applications. These features add to
the overall reliability of the PWR70XX Series by reducing
the possibility of inadvertently damaging the unit due to an
output overload.
The high efficiency of the PWR70XX Series means low
internal power dissipation. With less heat dissipated, the
PWR70XX Series can operate at higher ambient temperature
with no degradation of reliablility.
The PWR70XX 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.
