UMP Models www.murata-ps.com 25-40W, Single Output, DC/DC Converters OBSOLETE PRODUCT Last time buy: 04 January 2013 FEATURES Higher operating temperatures Fully potted Typical unit Designed to meet UL1950 and EN60950-1 (basic insulation) mark available (75V-input models) PRODUCT OVERVIEW DATEL's UMP Models are fully potted, 25-40 Watt DC/ DC converters designed to meet UL1950 and EN609501 safety standards. The combination of the UMP's higher efficiencies and thermally conductive potting compound enables these devices to achieve higher operating temperatures without derating. The 2" x 3" UMP "footprint" conforms with the standard pinout and pin geometries of most 3" x 3" devices (a 33% space savings) while delivering as much as 60% more power (40W vs. 25W). Applicable to a wide range of telecom, computer and other OEM applications, UMP Model DC/DC's operate from four input voltage ranges (10-36V for "Q12" models, 18-36V for "D24" models, 18-75V for "Q48" models, and 36-75V for "D48" models). Available output voltages are 5, 12 and 15 Volts. For reliability and affordability, DATEL exploits Fully isolated, 1500Vdc guaranteed 25/30/35/40W output power Standard pinout! Smaller size! New 2" x 3" package fits 3" x 3" footprint 5V, 12V or 15V outputs Four input voltage ranges: 10-36V, 18-36V 18-75V, 36-75V High efficiency (to 85%) Input under and overvoltage lockout VOUT trim and on/off control Modifications and customs for OEMs contemporary, high-speed, automatic assembly to construct the UMP's traditional, field-proven, SMTon-pcb designs. Devices employ corrosion-resistant metal cases with plastic headers. Heat generating transformer cores and power semiconductors are mounted directly to the cases, which have threaded inserts for add-on heat sinks or pcb mounting. Devices are specified for -40 to +100C operation and derating information is provided for operation with/ without heat sinks and forced air flow. All devices feature input pi filters, input undervoltage and overvoltage shutdown, output overvoltage protection, output current limiting, and thermal shutdown. UL, CSA, EN and IEC compliance testing is available (75V-input devices will be CE marked) as are full EMI/EMC characterizations.

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). /54054 ).054 K7 4URNS 42)- ,/!$ #/--/. 3 +10V #/--/. +INPUT 10k9 Figure 7.

Driving the On/Off Control Pin 42)- 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).

Trim Connections Using Fixed Resistors 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, UMP 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, must be connected to earth or chassis ground to ensure reliable operation. UMP Trim Resistor Equations Output Trimming The equations listed below will set the output to a desired voltage using a single fixed trim resistor if you do not prefer to use a potentiometer. Do not exceed 5% from the nominal output voltage. Trim resistors should have low temperature coefficients, 100ppm/C or less to ensure stability. Adjustment beyond the specified adjustment range is not recommended. Attach the trim resistors as close as practical to the converter. VOUT may be trimmed 5% via a single trimpot or fixed resistor. The trimpot should be connected between +Output (pin 9) and Common (pin 8) with its wiper connected to pin 10 (Trim). A trimpot can also be used to determine the value of a single fixed resistor which can be connected between pin 10 (Trim) and pin 9 (+Output) to trim "down" the output voltages, or between pins 10 (Trim) and 6 (-Output) to trim "up" the output voltages. Fixed resistors should be metal-film types with absolute TCR's less than 100ppm/C to ensure To trim the voltage higher than the nominal output, install the resistor between the trim pin and -VOUT terminal. stability. To trim the voltage lower than the nominal output, install the resistor between the trim pin and +VOUT terminal. 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. These equations are a starting point. The final output voltage at the load will vary slightly with load current, distance to the load (and voltage drop), input voltage, ambient temperature, airflow, initial setpoint accuracy and several other variables. For critical applications, you should measure the actual voltage obtained. 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_UMP25-40W_B04 Page 6 of 9 6 UMP Models 25-40W, Single Output, DC/DC Converters Trim Equations 5-0 1 5-0 1 24 $/7.

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 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. 80 40 60 40 20 20 0 0 Random Vibration (G's) Design for Reliability Typical HALT Profile 100 Temperature (C) These models are the latest DC/DC Converters to emerge from DATEL's new, company-wide approach to designing and manufacturing the most reliable power converters available. The five-pronged program draws our Quality Assurance function into all aspects of new-product design, development, characterization, qualification and manufacturing. -20 -40 10 20 30 40 50 60 70 80 90 Test Time (minutes) 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. 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. 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 "coldstart" capabilities. www.murata-ps.com/support MDC_UMP25-40W_B04 Page 8 of 9 UMP Models 25-40W, Single Output, DC/DC Converters Qualification In-Line Process Controls and Screening 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. 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 statistically sampled, charted and fine tuned as necessary.
