TMP Models www.murata-ps.com Triple Output, High-Efficiency, Smaller-Package, 25-40 Watt, DC/DC Converters OBSOLETE PRODUCT Last time buy: 04 January 2013 Features higher operating temperatures Fully potted Designed to meet UL 60950-1 and EN60950-1 (basic insulation) mark available (75V-input models) Fully isolated, 1500Vdc guaranteed 25/30/35/40W output power Standard pinout! Smaller size! 2" x 3" package fits 3" x 3" footprint +5V and ±12V or +5V and ±15V outputs Four input voltage ranges: 10-36V, 18-36V, 18-75V, 36-75V 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.

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.

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.

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.

Temperature Derating Without Heat Sink Figure 5b. Temperature Derating With Heat Sink 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."

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. ON/OFF CONTROL 2 –VIN Figure 6. Driving the On/Off Control Pin 9 +5V VOUT 3 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. +10V +VIN TRIM 10 2 –VIN 20k 5-10 Turns LOAD Trim Up 8 COMMON Figure 7.

That will place unnecessary force on the mounting pins. Instead, the converter is held securely by only soldering the mounting pins. OMMON C 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. www.murata-ps.com/support MDC_TMP25-40W_B05 Page 6 of 7 TMP Models Triple Output, High-Efficiency, Smaller-Package, 25-40 Watt, DC/DC Converters Soldering Guidelines Murata Power Solutions recommends the specifications below when installing these converters.
