The WPN20R series is a family of
high performance DC/DC converters
available in three input voltage ranges
of 9-18V, 18-36V and 33-75V. The unit
is housed in a space saving aluminum
shell and combines low cost with high
performance across all line and load
conditions. The 300KHz switching
frequency and forward converter
across all line and load conditions in a
space saving package. Other features
include: full regulation down to zero
load, under voltage lock-out, internal
temperature shutdown, soft start, remote
on/off and over current protection.
An output trim feature is provided,
assembled using a fully automated
process incorporating 100% surface
mounted components for increased
reliability.
Applications include: Telecom-
munications, Battery Powered Sytems,
Process Control Equipment,
allowing the user to compensate for long Transportation Equipment and
line lengths. The WPN20R Series is
Distributed Power Systems.
topology provide excellent performance

nits are encapsulated in a low
thermal resistance molding compound which
has excellent chemical resistance, wide
operating temperature range, and good
electrical properties under high humidity
environments. The encapsulant and outer shell
of the unit have UL94V-0 ratings. Lead material
is brass with a solder plated surface to allow
ease of solderability.
