ULS Series  
s
Sixteenth-brick DOSA-Compatible,  
Isolated DC/DC Converters  
FEATURES  
 ꢀSmall footprint DC/DC converter, ideal for  
high current applications  
 ꢀTiny 0.9" x 1.3" x 0.40" open frame package  
Typical unit  
 ꢀIndustry standard DOSA "brick" format  
and pinout  
PRODUCT OVERVIEW  
 ꢀ36-75 Volts DC input range  
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- On/Off control may use a switch, transistor or digital  
brick” width (0.9 inches) while still retaining a  
66 Watt output and full 2250 Volt DC isolation.  
The PC-board mount converter family accepts  
minimum load is required. For systems requiring  
controlled startup/shutdown, an external remote  
 ꢀ2250 Volt Basic input/output isolation  
(48V models)  
 ꢀUp to 66 Watts total output power with  
overtemperature shutdown  
logic. Remote Sense inputs compensate for resis-  
tive line drops at high currents.  
Many self-protection features on the ULS series  
 ꢀHigh efficiency synchronous rectifier forward  
topology  
36 to 75 Volts DC inputs and delivers fixed outputs avoid both converter and external circuit hazards.  
regulated to within 0.2ꢀ. 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 10ꢀ of  
nominal output while delivering fast settling to  
current step loads and no adverse effects from  
higher capacitive loads. Excellent ripple and noise  
specifications assure compatibility to circuits using  
CPU’s, ASIC’s, programmable logic and FPGA’s. No  
These include input undervoltage lockout and  
overtemperature shutdown. The outputs current  
limit using the “hiccup” autorestart technique and  
the outputs may be short-circuited indefinitely.  
Additional features include output overvoltage and  
reverse conduction elimination.  
The synchronous rectifier forward topology yields  
high efficiency for minimal heat buildup and “no  
fan” operation.  
 ꢀStable no-load operation with no required  
external components  
 ꢀOperating temperature range -40 to +85°C  
with derating  
 ꢀUL 60950-1, CSA-C22.2 No. 234,
