... 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 ...

... Nominal line voltage, no load/balanced full-power condition. Tested from no-load to 100% load (other output at no-load). Output trim may impact 5V load regulation. Optional Functions BWR 33 Watt DC/DC’s are designed with an On/Off Control function with positive polarity in the pin 4 position. L1 Pin length: 0.110 in. (2.79mm) ±0.010 L2 Pin length: 0.145 in. (3.68mm) ± ...

... The On/Off Control (pin 4) may be used for remote on/off operation. As shown in Figure 1, the control pin is referenced to the –Input (pin 2) and will be inter- nally pulled to a high state. The standard BWR model (no suffix) is designed so that it is enabled when the control pin is left open and disabled when the control pin is pulled low (less than +0.8V relative to – ...

... This on/off cycling is referred to as "hiccup" mode. Isolation/Case Connection The BWR 33 Watt Series’ 5V and 3.3V outputs (pins 5 & 7) and return (pin 6) are isolated from the +V an opto-coupled transistor. Case connections are made internal to the DC/DC converter. " ...

... It is recommended that fuses be installed in the +Input line. Trimming Output Voltages These BWR converters have a trim capability (pin 8) that allow users to adjust the output voltages ±5%. A trim adjustment will cause an equal percentage of change in both outputs. Adjustments to the output voltages can be accom- plished via a trim pot Figure single fi ...

... Options and Adaptations Optional Functions The dual output BWR 33W DC/DC converters offer two mechanical options. Per the Ordering Guide on page 2, the trailing DXX in each part number pertains to the base part number. Part-number suffixes are added after the “DXX,” indicat- ing the selection of standard options. The resulting part number is a “ ...
