Murata Power Solutions' UWQ series offers high output current (up to 20 A) in an industry-standard “quarter-brick” package requiring no heatsink for most applications. The UWQ series delivers fixed DC output voltages up to 240 W (12 V at 20 A) for printed circuit board mounting. Wide range inputs of 18 to 60 VDC (48 V nominal) are ideal for datacom and telecom systems. The UWQ-12/20-T48xS offers a load-sharing option for paralleling up to three modules in the most demanding, power hungry applications. The UWQ-12/20-T48xT is trimmable from 10.8 VOUT to 13.2 VOUT and includes Sense pins to compensate for voltage drops at the load. Advanced automated surface-mount assembly and planar magnetics deliver galvanic isolation rated at 2250 VDC for basic insulation. To power digital systems, the outputs offer fast settling to current steps and tolerance of higher capacitive loads. Excellent ripple and noise specifications assure compatibility to CPUs, ASICs, programmable logic, and FPGAs. No minimum load is required. For systems needing controlled startup/shutdown, an external remote On/Off control may use either positive or negative logic. A wealth of self-protection features include input under-voltage lockout and over-temperature shutdown using an on-board temperature sensor; overcurrent protection using the “hiccup” auto-restart technique, provides indefinite short-circuit protection, along with output OVP. The synchronous-rectifier topology offers high efficiency for minimal heat generation and “no heatsink” operation. The UWQ series is certified to safety standards UL/IEC/CSA 60950-1, 2nd edition. It meets Class B EMI conducted emission compliance to EN55022, CISPR22 with an external filter.
