DATEL’s new BPB Model, 25-40 Watt, dual-output DC/DC converters bring you efficient "on-board" power processing in a cost-effective smaller package with a standard pinout.The 2" x 3" BPB "footprint" conforms to the industry-standard pinout and pin geometries of most 3" x 3" devices (a 33% space savings) while delivering as much as 60% more power (40W vs. 25W).
Applicable to a wide range of telecom, computer and other OEM applications, BPB Model DC/DC’s offer ±5V, ±12V or ±15V outputs.They operate from four different input voltage ranges with total available output power being a function of the selected input range. "Q12" models operate from 10-36V and deliver 25W.
"Q48" models operate from 18-72V and deliver 30W. For "D24" and "D48" models, the input voltage ranges and rated output powers are 18-36V at 35W and 36-72V
at 40W, respectively.
For improved reliability and affordability, BPB Models exploit modern, high-speed, automatic assembly to construct their field-proven, SMT-on-pcb designs. Devices employ corrosion-resistant steel cases with heavy zinc top plates (traditionally referred to as baseplates). Heat-generating transformer cores and power semiconductors are mounted directly to the cases, which have threaded inserts for optional add-on heat sinks and/or pcb mounting.
All devices feature input pi filters, input overvoltage shutdown, output overvoltage protection, output current limiting, and thermal shutdown. UL, CSA, EN and IEC compliance testing is currently in progress as are EMI/EMC characterizations.

Typical at TA = +25°C under nominal line voltage and balanced "full-load" conditions unless otherwise noted.
For BPB devices, "full load" is a function of each device's input voltage range. See Output Power Considerations and Technical Notes for more details.
Ripple/Noise (R/N) measured over a 20MHz bandwidth.Balanced loads, 10% to 100% load.
Nominal line voltage, no-load/full-load conditions.

As shown below, BPB Model DC/DC Converters are classified by output power. For dual-output devices, the total output power from the two outputs can not exceed the rated power. For example, "Q48" models have a maximum output power of 30W. Therefore, if the +Output is sourcing 20 Watts, the –Output is limited to sourcing 10 Watts ensuring the total output power does not exceed 30 Watts.
