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.

As shown below, TMP Model DC/DC Converters are classified by output
power. For triple-output devices, the sum of the output power from the primary
+5V output and 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.

TECHNICAL NOTES
Filtering and Noise Reduction
All TMP 25-40 Watt DC/DC Converters achieve their rated ripple and noise
specifications without the use of external input/output capacitors. In criti-
cal applications, input/output ripple and noise may be further reduced by
installing electrolytic capacitors across the input terminals and/or low-ESR
tantalum or electrolytic capacitors across the output terminals. Output
capacitors should be connected between their respective output pin (pin 6, 7
or 9) and Common (pin 8). The caps should be located as close to the power
converters as possible. See Figure 7. Typical values are listed in the tables
below. In many applications, using values greater than those listed will yield
better results.

Contact our Applications Engineering Group for additional details.
Input Fusing
Certain applications and/or safety agencies may require the installation of

These converters require a minimum 10% loading on their primary output and 20%
loading on each auxiliary output to maintain specified regulation. Operation under no-load
conditions will not damage these devices; however they may not meet all listed specifica
tions.

"Full load" varies by part number and is determined by the input voltage range as indi
cated by the part number suffix. See Technical Notes and Output Power Considerations.

Output Power
TMP Model, triple-output DC/DC converters incorporate a design tradeoff be-
tween total available output power and input voltage range. The total available
power is a function of both the nominal input voltage and the "width" of the
input voltage range. For a given nominal input (24V or 48V), narrower ranges
(2:1 vs. 4:1) have more available power. For a given "width" of input range
(2:1 or 4:1), higher nominal inputs (48V vs. 24V) have more available power.
Each device, as indicated by its part-number suffix (Q12, Q48, D24, D48),
has a total output power limitation of 25, 30, 35 or 40 Watts, respectively.
Observing these power limitations is the user's responsibility.
As indicated by its Part Number Structure, each TMP device is capable of
sourcing up to 5 Amps of +5V current as well as ±1 Amp of auxiliary (±12V
or ±15V) currents. Users have the flexibility of loading any output up to these
limits; however, you must be extremely careful not to exceed the total output
power rating of any given device. If, for example, a device with a 30W power
rating is sourcing 4A from its +5V output (representing 20W of primary output
power), that device can only supply an additional 10W from its auxiliary outputs
(±333mA from ±15V outputs or ±417mA from ±12V outputs).
As a consequence of this "power-allocation" flexibility, the definition of "full
load," as the condition under which performance specifications are tested
and listed, is ambiguous. The following table lists the primary and auxiliary
output currents that DATEL uses to define each device’s "full load."
