DATEL’s TMP Models are fully potted, 25-40 Watt, triple-output DC/DC converters

designed to meet UL1950 and EN60950 safety standards.The TMP’s higher efficiencies

and thermally conductive potting compound enable these devices to achieve higher

operating temperatures without derating.The 2" x 3" TMP "footprint" conforms to the

standard pinout and pin geometries of most 3" x 3" devices (a 33% space savings) while

delivering 60% more power (40W vs. 25W).

Applicable to a wide range of telecom, computer and other OEM applications, TMP

Model DC/DC’s offer +5V and ±12V or +5V and ±15V outputs.They operate from four

different input voltage ranges with total available output power being a function of the

selected range. "Q12" models operate from 10-36V and deliver 25W. "Q48" models

operate from 18-75V and deliver 30W. For "D24" and "D48" models, the input ranges and

output powers are 18-36V at 35W and 36-75V at 40W, respectively.

TMP's employ corrosion-resistant metal cases with plastic headers. Heat-generating

transformer cores and power semiconductors are mounted to the

cases, which have threaded inserts for add-on heat sinks 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 compli-

ance testing is currently in progress (75V-input devices will be CE marked) as are full

EMI/EMC characterizations.
