Series Description

The world of “brick” DC/DC converters has seen a steady size reduction. The ULS series makes another dramatic size shrink down to a “sixteenthbrick” width (0.91 inches) while still retaining up to 30 Watt output and full 2250 Volt DC isolation. The PC-board mount converter family accepts 36 to 75 Volts DC inputs and delivers fi xed outputs regulated to within ±0.125%. 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 -20% to +10% of nominal output while delivering fast settling to current step loads and no adverse effects from higher capacitive loads. Excellent ripple and noise specifi 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.

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 indefinitely. Additional features include output overvoltage and reverse conduction elimination. The synchronous rectifier forward topology yields high efficiency
