Housed in miniature 2" x 1" x 0.375", 5-side shielded, metal packages with electrically non-conductive coatings, these power converters offer non-latching output current limiting, input overvoltage shutdown (except D5A models), input reverse-polarity protection, and output overvoltage clamping to protect both the power converters and their loads. As members of DATEL's new A-Series, the 8-11W triples feature 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 repeatable automatic-assembly techniques. Their superior durability is substantiated by a rigorous in-house qualification program that includes HALT (Highly Accelerated Life Testing). Each of these fully line and load-regulated switching DC/DC converters has a +5V primary output (with output current as high as 1A) and either 12V or 15V auxiliary outputs (with currents as high as 210mA). These devices were designed to power small analog/digital partitions in equipment employing distributed-power architectures with bus voltages between 4.7 and 72 Volts. Applications include computer/networking, telecom/datacom equipment, industrial instrumentation and automatic test equipment.

On "D48A" models, the case is connected to pin 1 (+VIN). www.murata-ps.com All A-Series TWR 8-11 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 4, 5 or 7) and Common (pin 6) as shown in Figure 2. 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.

Using External Capacitors to Reduce Input/Output Ripple/Noise If you're designing with EMC in mind, please note that all of DATEL's TWR 8-11 Watt A-Series DC/DC Converters have been characterized for radiated and conducted emissions in our new EMI/ EMC laboratory. Testing is conducted in an EMCO 5305 GTEM test cell utilizing EMCO automated EMC test software. Radiated emissions are tested to the limits of FCC Part 15, Class B and CISPR 22 (EN 55022), Class B. Correlation to other specifications can be supplied upon request. Radiated emissions plots to FCC and CISPR 22 for model TWR-5/1000-12/125-D5A appear below.

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 qualification 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 changes, stresses are stepped up again and the cycle is repeated until the "fundamental limit of the technology" is determined. DATEL 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 profile (shown above) consists of thermal cycling (-55 to +125C, 30C/minute) and simultaneous, gradually increasing, random longitudinal and rotational vibration up to 20G's with load cycling and applied-voltage extremes added as desired. Many devices in DATEL's new 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. Qualification For each new product, electrical performance is verified via a comprehensive characterization process and long-term reliability is confirmed via a rigorous qualification procedure. The qual procedure includes such strenuous tests as thermal shock and 500 hour life. Qual testing is summarized below. The goal of the accelerated-stress techniques used by DATEL 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 Accelerated Life Testing) repeatedly during the design and early manufacturing phases to detect potential electrical and mechanical design weaknesses that could result in possible future field failures. Qualification Testing During HALT, prototype and pre-production DC/DC converters are subjected to progressively higher stress levels induced by thermal cycling, rate of temperature change, vibration, power cycling, product-specific stresses (such as dc voltage variation) and combined environments. The stresses are not meant to simulate field environments but to expose any weaknesses in a product's electro/mechanical design and/or assembly 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.
