ULS 100-Watt Series www.murata-ps.com Sixteenth-brick DOSA-Compatible, Isolated DC-DC Converters FEATURES TTyypical units Industry standard DOSASixteenth-bric format and pinout with surface mount option PRODUCT OVERVIEWCT OVERVIEW 36-75 Volts DC input range, 3.3, 5 and 12 Vdc The new ULS 100 Watts series offers output minimum load is required. For systems requiring outputs. voltages of 3.3Vout (30A), 5Vout (20A) and 12Vout controlled startup/shutdown, an external remote 2250 Volt Basic input/output isolation (8.3A). The ULS sixteenth-brick series maintains On/Off control may use a switch, transistor or (48V models) a width of 0.9 inches while still retaining up to digital logic. Remote Sense inputs compensate for Up to 100 Watts total output power with 100 Watt output and full 2250 Volt DC isolation. resistive line drops at high currents. The PC-board mount converter family accepts Many self-protection features on the ULS series overtemperature shutdown 36to 75 Volts DC inputs and delivers xed outputs avoid both converter and external circuit hazards. High ef ciency half bridge synchronous regulated to within 0.2%. The ULS converters These include input undervoltage lockout and recti er topology are ideal for datacom and telecom applications, overtemperature shutdown. The outputs current 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 inde nitely. ULS outputs may be trimmed within 10% of Additional features include output overvoltage and 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 half bridge synchronous recti er topology Certi ed to UL 60950-1, CSA-C22.2 No. 234, higher capacitive loads. Excellent ripple and noise yields high ef ciency for minimal heat buildup and EN60950-1 safety approvals, 2nd Edition speci cations assure compatibility to circuits using no fan operation. Extensive self-protection shut down features CPUs, ASICs, programmable logic and FPGAs.
