Murata Power Solutions’ 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 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.
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.

Isolation Voltage ➃
1500Vdc, minimum
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.

➀ 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 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.
➃ Listed specification is for input-to-output isolation. Input-to-case and output-to-case isolation
is 1000Vdc, minimum.

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 Murata Power Solutions uses to define each device’s "full
load."

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 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).
3
10k
5
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.

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).
Trim Down
+VIN
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.

Threaded Inserts and Heatsink Installation
CAUTION: Do not use the threaded inserts to bolt the converter down to a
PC board. That will place unnecessary force on the mounting pins. Instead,
the converter is held securely by only soldering the mounting pins.

Figure 8. Trim Connections Using Fixed Resistors
When attaching the heat sink from above the converter, use a maximum
torque of 2 inch-pounds (0.23 N-m) on the 4-40 bolts to avoid damaging the
threaded inserts. Use a tiny amount of fastener adhesive or 4-40 lockwashers to secure the bolts.
