safety approvals
The world of “brick” DC-DC converters has seen
a steady size reduction. The UWS series makes
another dramatic size shrink down to a “sixteenth-
brick” width (0.90 inches) while still retaining a
high power output and full 2250 Volt DC isolation.
The PC-board mount converter family accepts
18?to 75 Volts DC inputs and delivers ?xed outputs
regulated to within ±0.125%. The UWS converters
are ideal for datacom and telecom applications,
cell phone towers, data centers, server farms and
network repeaters.
UWS outputs may be trimmed while delivering
fast settling to current step loads and no adverse
effects from higher capacitive loads. Excellent ripple
and noise speci?cations assure compatibility to cir-
cuits using CPU’s, ASIC’s, programmable logic and
FPGA ’s. No minimum load is required. For systems
requiring controlled startup/shutdown, an external
remote On/Off control may use a switch, transistor
or digital logic.
Many self-protection features on the UWS series
avoid both converter and external circuit hazards.
These include input undervoltage lockout and
overtemperature shutdown. The output of these
DC-DC converters have current limit using the
“hiccup” autorestart technique and the outputs may
be short-circuited inde?nitely. Additional features
include output overvoltage and reverse conduction
elimination.
The synchronous recti?er forward topology yields
high ef?ciency for minimal heat buildup and “no
fan” operation.
