UWR Models www.murata-ps.com Single Output, High-Density, 6 Amp/15 Watt DC/DC Converters Typical units PRODUCT OVERVIEW FEATURES n 1.2-2.5VOUT models source 6 Amps n 3.3VOUT models source 4.25 Amps n 5/12/15VOUT models deliver full 15 Watts n Synchronous-rectifier topologies n Guaranteed efficiencies to 88% n Choice of 3 input voltage ranges: 10-18V, 18-36V, 36-75V n –40 to +60/70°C ambient w/o derating n Fully isolated (1500Vdc); I/O protected n Meets UL/IE/EN60950-1 certification, 2nd Edition n CE mark (75VIN models) The new 1.2, 1.5V, 1.8V and 2.5V models in Murata Power Solutions’ flagship 7-15 Watt A-Series can source a continuous 6 Amps. This is the most "low-voltage" current available from a standard 1" x 2" package, and these power converters exemplify Murata Power Solutions’ relentless drive to bring you more power/current, from standard packages, without compromising reliability or resorting to thermal specmanship. By combining a high-frequency, high-efficiency (to 88%), synchronous-rectifier topology with the newest components and time-tested, fully automated, SMT-on-pcb construction, these UWR Models are able to bring you 7-15W (@ up to 6A) in the standard 1" x 2" package from which most competitors can only get 5-10W (@ 3-4A). All UWR’s deliver their full output power over ambient temperature ranges from –40°C to as high as +70°C (model and input voltage dependent) with- out heat sinks or supplemental forced-air cooling. Devices derate to +100°C. Output voltages are 1.2, 1.5, 1.8, 2.5, 3.3, 5, 12 or 15 Volts. Input voltage ranges are 10-18V (D12 models), 18-36V (D24 models) or 36-75V (D48 models). All models feature input pi filters, input undervoltage and overvoltage lockout, input reverse-polarity protection, output overvoltage protection, output current limiting, and continuous short-circuit protection. On/ off control and output-trim functions are optional (see Optional Functions). All models are designed to meet IEC950, UL1950 and EN60950-1, 2nd Edition safety requirements. D48 models (36-75V inputs) are CE marked. UWR 7-15W DC/DC’s are packaged in low-cost, light-weight, diallyl phthalate (UL94V-0 rated) plastic packages with standoffs. EMC compliance is achieved via a low-noise design rather than through expensive metal shielding. n Standard 1" x 2" packages and pinouts n Optional VOUT trim and on/off control +VIN (1) +VOUT (4) SWITCH CONTROL COMMON (6) –VIN (2) PWM CONTROLLER ON/OFF CONTROL (3) (OPTIONAL) OPTO ISOLATION REFERENCE & ERROR AMP TRIM (5) (OPTIONAL) UVLO & OVLO COMPARATORS Typical topology is shown.
