Triple Output

TPB Models

High-Efficiency, Smaller-Package

25-40 Watt, DC/DC Conver ters

Features DA TEL’s new TPB Model, 25-40 Watt, triple-output DC/DC pow er converters bring

you efficient "on-board" power processing in a cost-effective smaller package with a
standard pinout. The 2" x 3" TPB "f ootprint" conforms with 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, TPB
Model DC/DC’s operate from f our input voltage ranges (10-36V f or "Q12" models, 18­36V for "D24" models, 18-72V for "Q48" models, and 36-72V for "D48" models).
Availab le output voltages are +5 and ±12V or +5 and ±15V .

For improved reliability and aff ordability , DATEL uses contemporary , high-speed,
automatic-assembly techniques to construct the TPB’ s traditional, field-proven, SMT-on­pcb 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 baseplates, which also have threaded
inserts for add-on heat sinks or pcb mounting. T emper ature derating information is
provided for operation with and without heat sinks and forced air flo w.

All devices feature input pi filters, input overvoltage shutdown, output overvoltage
protection, output current limiting, and thermal shutdown. All units are temperature
cycled, burned in and automatically tested prior to shipment. UL, CSA, EN and IEC
compliance testing is currently under way as are full EMI/EMC characterizations.

MECHANICAL SPECIFICATIONS

As shown below, TPB Model DC/DC Converters are classified by output power.
For triple-output devices, the sum of the output power from the primary +5V
output plus that from the two auxiliary (±12V or ±15V) outputs can not exceed
the rated power. For example, "D24" models have a maximum power of 35W.
Therefore, if you source the maximum primary current of 5A, the devices will
only be able to provide 10W of total power from their auxilliary outputs.
