DC/DC regulator
Input 8.3 - 16 V
Output 16 A
Key Features
• Wide input, 8.3 - 16 Vdc
• Programmable output, 0.75 - 5.5 Vdc
• Monotonic start up into pre-biased output
• Under voltage protection
• Short circuit protection
• Remote sense
• Remote On/Off
• Design for Environment (DfE)
• European Commission Directive 2002/95/EC
(RoHs) compliant
The PMC series of surface mount DC/DC regulators
(POL) are intended to be used as local distributed power
sources in distributed power architecture. The high ef-
ficiency and high reliability of the PMC series makes them
particularly suited for the communications equipment of
today and tomorrow.
These products are manufactured using the most ad-
vanced technologies and materials to comply with en-
vironmental requirements. Designed to meet high reliability
requirements of systems manufacturers, the PMC responds
to world-class specifications.
Ericsson Power Modules is an ISO 9001/14001 certified
supplier.

Stress in excess of Absolute Maximum Ratings may cause permanent damage. Absolute Maximum Ratings, sometimes referred to as no destruction limits, are
normally tested with one parameter at a time exceeding the limits of Output data or Electrical Characteristics. If exposed to stress above these limits, function
and performance may degrade in an unspecified manner.
