Devices deliver any combination of primary plus auxiliary power as long as the total output power does not exceed 20 Watts. This feature enables designers to select a single device to fulfi ll any number of different require- ments. As members of MPS’s new A-Series, the 20W triples exhibit both low cost and outstanding long-term reliability. Their design combines straightforward circuit topologies, the newest components, proven SMT-on-pcb construction methods, and highly repeat- able automatic-assembly techniques. Their superior durability is substantiated by a rigorous in-house qualifi cation program that includes HALT (Highly Accelerated Life Testing). Each device has a +5V primary output and either ±12V or ±15V auxiliary outputs. “D12A” models achieve fully rated performance with inputs ranging from 9 to 36 Volts. “D48A” models operate over an input range of 18-75 Volts. These full-featured triples have non-latching output current limiting, input overvoltage shutdown, input reverse-polarity protection, and output overvoltage clamping to protect both the power converters and their loads. SIMPLIFIED SCHEMATIC PRODUCT OVERVIEW Among the three families of triple-output DC/DC converters in MPS’s A-Series, the 20W 2" x 2" devices are distinguished by their unique “power-sharing” architecture.

Proper operation under conditions other than those listed in the Performance/Functional Specifi cations Table is not implied. Filtering and Noise Reduction All A-Series TWR 20 Watt DC/DC Converters achieve their rated ripple and noise specifi cations without the use of external input/output capacitors. In critical applications, input/output 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 5, 6 or 8) and Common (pin 7). The caps should be located as close to the power converters as possible. Typical values are listed below. In many applications, using values greater than those listed will yield better results.

Con- tact 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 MPS A-Series TWR

20 Watt DC/DC Converters, you should use slow-blow type fuses with values

no greater than 4A for “D12A” models and 2A for “D48A” models. On/Off Control The On/Off Control pin (pin 4) may be used for remote on/off operation. A TTL logic high (+2 to +5 Volts, 250μA max.) applied to pin 4 disables the converter. A TTL logic low (0 to +0.8 Volts, 70μA max.), or no connection, enables the converter. Control voltages should be referenced to pin 2 (–Input). Applying a voltage to the Control pin when no input power is applied to the converter can cause permanent damage to the converter.

20W, Triple Output DC-DC Converters MDC_TWR20W.E02 Page 7 of 8 www.murata-ps.com/support Quality and Reliability The A-Series are the fi rst DC/DC Converters to emerge from MPS’s new, company-wide approach to designing and manufacturing the most reliable power converters available. The fi ve-pronged program draws our Quality Assurance function into all aspects of new-product design, development, characterization, qualifi cation and manufacturing. Design for Reliability Design for Reliability is woven throughout our multi-phased, new-product- development process. Design-for-reliability practices are fully documented and begin early in the new-product development cycle with the following goals: 1. To work from an approved components/vendors list ensuring the use of reliable components and the rigorous qualifi cation of new components. 2. To design with safety margins by adhering to a strict set of derating guidelines and performing theoretical worst-case analyses. 3. To locate potential design weaknesses early in the product-development cycle by using extensive HALT (Highly Accelerated Life Testing). 4. To prove that early design improvements are effective by employing a thorough FRACA (Failure Reporting Analysis and Corrective Action) system. HALT Testing The goal of the accelerated-stress techniques used by MPS is to force device maturity, in a short period of time, by exposing devices to excessive levels of “every stimulus of potential value.” We use HALT (Highly Acceler- ated Life Testing) repeatedly during the design and early manufacturing phases to detect potential electrical and mechanical design weaknesses that could result in possible future fi eld failures. During HALT, prototype and pre-production DC/DC converters are sub- jected to progressively higher stress levels induced by thermal cycling, rate of temperature change, vibration, power cycling, product-specifi c stresses (such as dc voltage variation) and combined environments. The stresses are not meant to simulate fi eld environments but to expose any weaknesses in a product’s electro/mechanical design and/or assem- bly processes. The goal of HALT is to make products fail so that device weaknesses can be analyzed and strengthened as appropriate. Applied stresses are continually stepped up until products eventually fail. After corrective actions and/or design changes, stresses are stepped up again and the cycle is repeated until the “fundamental limit of the technology” is determined. MPS has invested in a Qualmark OVS-1 HALT tester capable of applying voltage and temperature extremes as well as 6-axis, linear and rotational, random vibration. A typical HALT profi le (shown above) consists of thermal cycling (–55 to +125°C, 30°C/minute) and simultaneous, gradually increas- ing, random longitudinal and rotational vibration up to 20G’s with load cycling and applied-voltage extremes added as desired. Many devices in MPS’s A-Series could not be made to fail prior to reaching either the limits of the HALT chamber or some previously known physical limit of the device. We also use the HALT chamber and its ability to rapidly cool devices to verify their “cold-start” capabilities. Qualifi cation For each new product, electrical performance is verifi ed via a comprehen- sive characterization process and long-term reliability is confi rmed via a rigorous qualifi cation procedure. The qual procedure includes such strenu- ous tests as thermal shock and 500 hour life. Qual testing is summarized below. In-Line Process Controls and Screening A combination of statistical sampling and 100% inspection techniques keeps our assembly line under constant control. Parameters such as solder-paste thickness, component placement, cleanliness, etc. are statisti- cally sampled, charted and fi ne tuned as necessary. Visual inspections are performed by trained operators after pick-and-place, soldering and cleaning operations. Units are 100% electrically tested prior to potting. All devices are temperature cycled, burned-in, hi-pot tested and fi nal-electrical tested prior to external visual examination, packing and shipping. Rapid Response to Problems MPS employs an outstanding corrective-action system to immediately address any detected shortcomings in either products or processes. When- ever our assembly, quality or engineering personnel spot a product/process problem, or if a product is returned with a potential defect, we immediately perform a detailed failure analysis and, if necessary, undertake corrective actions. Over time, this system has helped refi ne our assembly operation to yield one of the lowest product defect rates in the industry.

20 Watt Converter Operational Details

There are several operational details of the 20W TWR series to be aware of when applying these converters.

20 Watts maximum power

The total maximum power for all outputs is 20 Watts. This is the sum of each separate output. Any one output may achieve its maximum power as long as the sum of all outputs for the whole converter does not exceed 20 Watts. For example, using model TWR-5/3000-15/500-D12A, if the maxi- mum power is drawn from the two ±15 Volt supplies, this produces 15 Watts (7.5 W plus 7.5 W) total power. The 5V output may then deliver 5 Watts maximum (not 15W) so that the total converter power is 7.5W+7.5W+5W=20W. Regulation Differences Between Outputs Looking at the Schematic diagram, observe that magnetic energy driven from the primary side affects all three outputs simultane- ously since they share a common transformer in combination a with magnetically coupled output inductor. We see that the regulation feedback is derived directly from the 5 Volt output and indirectly from the 12/15V outputs. Increasing current on the 12/15V outputs absorbs magnetic energy driving the 5V output therefore reduc- ing the 5V output voltage. Regulation compensates for this drop in output voltage but not to the same extent as the 5V output regula- tion. Short-circuit Conditions Because of the interconnected regulation and common transformer, a short circuit on one output will cause a voltage reduction on the remaining unshorted outputs. This effect is more pronounced for the 5V superior output vs. the 12/15V subordinate outputs. That is, a 5V short essentially places the PWM controller in power-limit mode whereas a 12/15V short may leave some partial power available on the remaining outputs. Time limits on short circuits The 5V output will tolerate 5 minutes maximum short circuit time at +25 deg.C. For the 12/15V outputs, short ciruits must limit to 30 seconds at +25 deg.C. Failure to remove the short circuits within these time limits may damage the converter or cause permanent operational changes. Higher ambient temperatures require reduced short circuit times. As long as shorts or overcurrents are removed within these time limits, the outputs will automatically recover to normal operation. As a practical matter, since it is diffi cult to control short circuit duration, make sure that the application is highly unlikely to cause a short circuit or the input is disconnected by means of a circuit breaker or fuse. The Three Outputs are not isolated from each other The three outputs share a common ground return which is fully isolated from the primary input side but not between each other. Therefore do not apply the outputs to applications which require isolation between the 5V and 12/15V sections.
