muRata UWS-5/10-Q48PM-C

The UWS-Q48 series makes another dramatic size shrink down to a “sixteenth brick” width (0.9 inches) while still retaining a high power output and full 2250 Volt DC I/O isolation. The converter family accepts 18 to 75 Volts DC inputs and delivers fixed regulated outputs. The UWS converters are ideal for mobile applications, datacom and telecom applications, cell phone towers, data centers, server farms and network repeaters. The UWS outputs may be trimmed 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 minimum load is required. For systems requiring controlled startup/shutdown, the external remote On/Off control may use an open collector switch transistor. Many self-protection features on the UWSQ48 series avoid both converter and external circuit hazards. These include input undervoltage shutdown and overtemperature shutdown. The output of these DC-DC converters have 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 flyback topology yields high efficiency for minimal heat buildup and “no fan” operation.
