DATEL’s 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.
