Triple Output

TMP Models

High-Efficiency, Smaller-Package

25-40 Watt, DC/DC Conver ters

Features

DA TEL’s new TMP Models are fully potted, 25-40 Watt, triple-output DC/DC con verters
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 off er +5V and ±12V or +5V and ±15V outputs. They operate from f our
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 r anges 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 compli­ance testing is currently in progress (75V -input devices will be CE marked) as are full
EMI/EMC characterizations.

MECHANICAL SPECIFICATIONS

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.

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; how ev er they ma y not meet all listed specifications.

➁

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

➂

Applying a voltage to the On/Off Control pin when no input power is applied to the converter
can cause permanent damage to the converter. If desired, the On/Off Control function can be
replaced with a Sync function. See page 6 of this data sheet f or more details.

➃

Listed specification is for input-to-output isolation. Input-to-case and output-to-case

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 critical
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.

In critical, space-sensitive applications, DATEL may be able to tailor the
internal input/output filtering of these units to meet your specific require­ments. Contact our Applications Engineering Group for additional details.

Input Fusing

Certain applications and/or safety agencies may require the installation of
fuses at the inputs of power conversion components. For DATEL TMP
DC/DC Converters, you should use slow-blow type fuses with values no

Definition of "Full Load" for Specification Purposes

Output Power

TMP Model, triple-output DC/DC converters incorporate a design tradeoff
between 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."

Table 1. Output Currents Comprising "Full Load"

25-40W, TRIPLE OUTPUT DC/DC CONVERTERS

XMP Series

6

On/Off Control (Standard)
The On/Off Control pin (pin 5) may be used for remote on/off operation. As
shown in Figure 6, the control pin has an internal 10k

Ω

pull-up resistor to
approximately 10V. The converter is designed so that it is enabled when the
control pin is left open (normal mode) and disabled when the control pin is
pulled low (to less than +0.8V relative to –Input, pin 2).

Dynamic control of the on/off function is best accomplished with a mechani­cal relay or an open-collector/open-drain drive circuit (optically isolated if
appropriate). The drive circuit should obviously be able to sink approximately
1mA when activated and withstand more than 10 Volts when deactivated.

Applying an external voltage to pin 5 when no input power is applied to the
converter can cause permanent damage to the converter. The on/off control
function, however, is designed such that the converter can be disabled (pin 5
pulled low) while input power is ramping up and then "released" once the
input has stabilized. Under these circumstances, it takes approximately
30ms for the output of the fully loaded DC/DC to ramp up and settle to within
±1% of its final value after the converter has been turned on.

Synchronization (Optional)
In critical applications employing multiple switching DC/DC converters, it may

be desirable to intentionally synchronize the switching of selected converters
(so the system noise can be reduced with notch filtering) or to purposely
desynchronize the converters (to lessen the current-carrying requirements on
intermediate dc buses). TMP DC/DC Converters have been designed so that
the On/Off Control function on pin 5 can be replaced with a Sync function. This
change has to be implemented by DATEL during the product assembly
process. Contact our Applications Engineering Group for additional details.

To synchronize the switching of multiple TMP converters configured with the
Sync function, an external clock can be applied to pin 5 of each converter.
The clock should be a TTL square wave referenced to –Input (logic high =
+2 to +5 Volts, 250µA max.; logic low = 0 to +0.8 Volts, 70µA max.) with a
maximum 1µsec "high" duration. The frequency of the synchronizing clock
should be higher than that of any individual converter. Therefore, it should be
145kHz ±5kHz.

Output Trimming

The +5V output may be trimmed ±6% via a single external trimpot or fixed
resistor. The trimpot should be connected as shown in Figure 7 with its wiper
connected to pin 10 (Trim). A trimpot can also be used to determine the value
of a single fixed resistor which should be connected as shown in Figure 8.
Connect the resistor between pin 10 (Trim) and pin 9 (+5V Output) to trim
"down" the output voltage. Connect the resistor between pins 10 and 8
(Common) to trim "up" the output voltage. Fixed resistors should be metal-film
types with absolute TCR’s less than 100ppm/°C to ensure stability.

Case Connection

Unlike most other DC/DC converters, TMP DC/DC's do not have their metal
case connected to one of their input pins. The "uncommitted" case is
connected to pin 4 which, depending on your system configuration, should be
connected to either +Input (pin 3) or –Input (pin 2).
