PMA Series
E
The PMA series of DC/DC regulators (POL) are
intended to be used as local distributed power
sources in distributed power architecture level 4. The
PMA series use a ceramic substrate with fine-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 efficiency. The
high efficiency makes it possible to operate over a
wide temperature range, without adding any external
heat 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 profile 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). The flat case top enables pick-and-place
handling and provides a surface for attachment to
cooling surfaces in areas with limited air flow.
These products are manufactured using the most
advanced technologies and materials to comply with
environmental requirements. Designed to meet high
reliability requirements of systems manufacturers, the
PMA responds to world-class specifications.
