PT4100—48V

15 Watt Isolated DC-DC Converter

SLTS021A

(Revised 1/16/2001)

The PT4100—48V series of dc/dc

isolated power in a single low-profile

module. Designed to operate from a

standard 48V telecom bus, these modules

employ switching frequencies of up to

850kHz, planar magnetics, and surface-

mount construction. They are designed

for Telecom, Industrial, Computer, Medical,

and other distributed power applications

that require input-to-output isolation.
