BWR-5/6-3.3/7-D12-C

Dual Output BWR Models www.murata-ps.com Mixed Voltage, 5V AND 3.3V, 2” x 2” 33 Watt DC/DC Converters Typical units FEATURES PRODUCT OVERVIEW  Regulated 3.3V and 5V outputs  5V @ 6Amps/3.3V @ 7 Amps capability For applications requiring 33 watts of power from 5V and 3.3V, DATEL offers a new power sharing DC/DC converter capable of meeting your output current requirements. The BWR-5/6-3.3/7-D48 (36-75V input), BWR-5/6-3.3/7-D24 (18-36V input) and BWR-5/6-3.3/7-D12 (10-18V input) are fully isolated DC/DC converters capable of delivering any combination of 5V and 3.3V loading up to a combined total of 33 Watts of output power. Housed in a standard 2" x 2" x 0.45" metal package coated with electrically non-conductive finish, these converters utilize a shared controlloop system to assure load regulation of ±1% for 3.3V output and ±1.5% for 5V output. All models include input Pi filtering, input overvoltage and  33 Watts total output power  No-load operation  Available input voltage ranges: 10-18V, 18-36V or 36-75V  Small 2" x 2" x 0.45" package  UL1950 and EN60950-1 safety approvals  mark available (75V-input models)  Continuous short-circuit protection  Fully isolated, 1500Vdc guaranteed  –40 to +100°C operating temperature  Input under and overvoltage shutdown undervoltage shutdown circuitry, output overvoltage protection, output short-circuit and current limiting protection, and thermal shutdown. Each design also provides trim capability and on/off control function. Fully synchronous output rectification renders high efficiency and no-load operation. BWR power sharing modules offer low ripple and noise performance, high efficiency (88%), 1500Vdc of isolation voltage, and are fully specified for –40 to +100°C operation. These devices meet IEC950, UL1950 and EN6950 safety standards, including BASIC insulation requirements for “D48” models. CB reports are available on request. “D48” models are CE marked (meet LVD requirements).  Output overvoltage protection  Thermal shutdowns +5V OUTPUT (5) +INPUT (1) SWITCH CONTROL +3.3V OUTPUT (7) –INPUT (2) ON/OFF CONTROL (4) OUTPUT RETURN (6) PWM CONTROLLER ACTIVE BLEEDER OPTO ISOLATION UV & OV COMPARATORS REFERENCE & ERROR AMP THERMAL SHUTDOWN TRIM (8) Typical topology is shown.
