Regulated 3.3V and 5V outputs @ 7 Amps capability 33 Watts total output power No-load operation Available input voltage ranges: or 36-75V Small x 0.45" package UL1950 and EN60950 safety approvals mark available (75V-input models) Continuous short-circuit protection Fully isolated, 1500Vdc guaranteed to +100°C operating temperature Input under and overvoltage shutdown Output overvoltage protection Thermal shutdown
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 to a combined total of 33 Watts of output power. Housed in a standard x 0.45" metal package coated with electrically nonconductive finish, these converters utilize a shared control-loop 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 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 1500Vdc of isolation voltage, and are fully specified for 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).

Balanced "full-load" @ 5A. All models are specified with external 1µF ceramic output capacitors. See Technical Notes/Graphs for details. Applying a voltage to On/Off Control (pin 4) when no input power is applied to the converter may cause permanent damage. Output noise may be further reduced with the installation of additional external output capacitors. See Technical Notes. On/Off control is designed to be driven with open collector or by appropriate voltage levels. Voltages must be referenced to the input return pin (Input). Demonstrated MTBF available on request.
