The world of “brick” DC/DC converters has seen
a steady size reduction. The ULS series makes
another dramatic size shrink down to a “sixteenth-
brick” width (0.9 inches) while still retaining up
to 66?Watt output and full 2250 Volt DC isolation.
The PC-board mount converter family accepts
36?to 75 Volts DC inputs and delivers ?xed outputs
regulated to within ±0.2%. The ULS converters
are ideal for datacom and telecom applications,
cell phone towers, data centers, server farms and
network repeaters.
ULS outputs may be trimmed within ±10% of
nominal output 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 circuits 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. Remote Sense inputs compensate for resis-
tive line drops at high currents.
Many self-protection features on the ULS series
avoid both converter and external circuit hazards.
These include input undervoltage lockout and
overtemperature shutdown. The outputs 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.
