UWQ-12/20-T48 Series www.murata-ps.com Wide Input, Isolated DOSA Quarter Brick DC-DC Converters PRODUCT OVERVIEW The UWQ series offers high output current (up to ripple and noise specifications assure compatibility 20 Amps) in an industry standard quarter brick to CPUs, ASICs, programmable logic and FPGAs. package requiring no heat sink for most applications. No minimum load is required. For systems needing The UWQ series delivers fixed DC output voltages up controlled startup/shutdown, an external remote On/ to 240 Watts (12V 20A) for printed circuit board Off control may use either positive or negative logic. mounting. Wide range inputs of 18 to 60 Volts DC A wealth of self-protection features include input Typical unit (48 Volts nominal) are ideal for datacom and telecom undervoltage lockout and overtemperature shutdown systems. using an on-board temperature sensor overcurrent FEATURES The UWQ-12/20-T48xS offers a load sharing protection using the hiccup auto restart technique, option for paralleling up to three modules in the provides indefinite short-circuit protection, along with Fixed DC outputs, 12V 20A most demanding, power hungry applications.
