PRODUCT OVERVIEW

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 load-

ing up to a combined total of 33 Watts of output

power.

package coated with electrically non-conductive

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

... 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 – ...
