Dual Output

BPB Models

High-Efficiency, Smaller-Package

25-40 Watt, DC/DC Conver ters

Features DATEL’s new BPB Model, 25-40 Watt, dual-output DC/DC con verters 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 off er ±5V , ±12V or ±15V outputs. They operate from four diff erent 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, respectiv ely .

For improved reliability and aff ordability , 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.

25-40W, DUAL OUTPUT DC/DC CONVERTERS

XPB Series

2

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.
