ULS 60-Watt Series www.murata-ps.com Sixteenth-brick DOSA-Compatible, Isolated DC/DC Converters FEATURES n Small footprint DC/DC converter, ideal for high current applications Typical unit n Tiny 0.9 x 1.3 x 0.40 open frame package n Industry standard DOSAbric format and pinout with surface mount option PRODUCT OVERVIEW n 36-75 Volts DC input range The world of brick DC/DC converters has seen minimum load is required. For systems requiring a steady size reduction. The ULS series makes controlled startup/shutdown, an external remote n 2250 Volt Basic input/output isolation another dramatic size shrink down to a sixteenth- On/Off control may use a switch, transistor or digital (48V models) brick width (0.9 inches) while still retaining up logic. Remote Sense inputs compensate for resis- n Up to 66 Watts total output power with to 66Watt output and full 2250 Volt DC isolation. tive line drops at high currents. overtemperature shutdown The PC-board mount converter family accepts Many self-protection features on the ULS series 36to 75 Volts DC inputs and delivers fixed outputs avoid both converter and external circuit hazards. n High efficiency synchronous rectifier forward regulated to within 0.2%. The ULS converters These include input undervoltage lockout and topology are ideal for datacom and telecom applications, overtemperature shutdown. The outputs current n Stable no-load operation with no required cell phone towers, data centers, server farms and limit using the hiccup autorestart technique and external components network repeaters. the outputs may be short-circuited indefinitely. ULS outputs may be trimmed within 10% of Additional features include output overvoltage and n Operating temperature range -40 to +85C nominal output while delivering fast settling to reverse conduction elimination. with derating current step loads and no adverse effects from The synchronous rectifier forward topology yields n Certified to UL 60950-1, CSA-C22.2 No. 234, higher capacitive loads. Excellent ripple and noise high efficiency for minimal heat buildup and no EN60950-1 safety approvals, 2nd Edition specifications assure compatibility to circuits using fan operation. n Extensive self-protection shut down features CPUs, ASICs, programmable logic and FPGAs.
