PMA Series
E
The PMA series of DC/DC regulators are intended
to be used as local distributed power sources in
distributed power architecture level 4. The PMA
series use a ceramic substrate with fi ne-pitch
components technology and a high degree of silicon
integration. Together with the electrical design using
low Rds-On MOSFET, this provides excellent thermal
management, high reliability and high effi ciency.
The high effi ciency makes it possible to operate over a
wide temperature range, without adding any external
dissipator. At forced convection cooling >1 m/s
(200 lfm), the PMA typically delivers full power up to
+80 ˚C ambient temperature.
The high reliability and the low profi le of the
PMA series makes them particularly suited for the
communications equipment of today and tomorrow
and applications with board spacing down to 15
mm (0.6 in). These products are manufactured using
the most advanced technologies and material to
comply with environmental requirements. Designed
to meet high reliability requirements of systems
manufacturers, the PMA responds to world-class
specifi cations and has a fi ve-year warranty.
