DATEL’s TMP Models are fully potted, 25-40 Watt, triple-output DC/DC converters
designed to meet UL 60950-1 and EN60950-1 safety standards. The TMP’s higher ef-
ﬁciencies 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 sav-
ings) 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 func-
tion 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-generat-
ing transformer cores and power semiconductors are mounted to the
cases, which have threaded inserts for add-on heat sinks.
All devices feature input pi ﬁlters, input overvoltage shutdown, output overvoltage
protection, output current limiting, and thermal shutdown.
