Io=3A non-isorated step-down DC/DC Converter module MPM00 Series SANKEN ELECTRIC CO., LTD. Jul/10/2013 Rev.1.0 1 http://www.sanken-ele.co.jp General Descriptions The MPM series is a full molded hybrid IC which contains a non-insulated buck type DC/DC converter in one package. A power supply circuit can be composed in a simple way by using this hybrid IC which requires a small part count. By connecting only an input smoothing electrolytic capacitor, an output smoothing electrolytic capacitor and an output voltage setting resistor, the hybrid IC can be operated. Because of this simple composition, time required for design evaluation is significantly reduced. Since a power inductor is built in, it is not required to select and evaluate the inductor separately . By adopting a full molding package which can be fitted to the heat sink by screwing, board mounting can be made in self-supporting state without the heat sink subject to the output voltage setting and load conditions. Features & Benefits Current mode type synchronization rectification PWM control system By connecting only an input smoothing electrolytic capacitor, an output smoothing electrolytic capacitor and an output voltage setting resistor, the hybrid IC can be operated. Since a power inductor is built in, it is not required to select and evaluate the inductor separately .

(11) The efficiency can be calculated by the equation 1 as follows: (12) The line/load regulation does not include any set deviation of output voltage. It should be noted that the deviation of set output voltage is affected by the accuracy of the external RFB. As for details, please refer to the fig.10. (13) At the time of setting the output voltages except V o = 12V , it should be noted that the OCP operation point may fluctuate from the values of V o = 12V because the inductance of the built-in coil and the frequency are constant.

Jul/10/2013 Rev.1.0 7 http://www.sanken-ele.co.jp About thermal derating curve of output current *It is a setup of commonness of MPM01/04. Thermal derating curve of the figure 6 is without the radiator which is a standard use condition fundamentally of MPM01/04. By the use of cooling-fan / radiator installation, output current beyond 3A can't be agreed. OCP(overcurrent protection) threshold value can't be changed, because it is fixed by built-in MIC. *With package design of MPM00, though radiator installation is possible by the screw, keep the following strictly: 1) You must surely use load current with less than 3Amps. 2) You must use the radiator of the form that package surface temperature is less than 100℃. (But, ambient temperature "Ta" makes 85℃ an upper limit.) Block diagram *It is a setup of commonness of MPM01/04.

Io=3A non-isorated step-down DC/DC Converter module MPM00 Series SANKEN ELECTRIC CO., LTD. Jul/10/2013 Rev.1.0 8 http://www.sanken-ele.co.jp A design guide for add-on parts . (1)Input capacitor “Cin” ・If output impedance of the VIN power supply is ideally endless and it is near-zero, the ripple-current doesn't flow to Cin. To make stabilize movement of MPM01/04, You must connect the input capacitor "Cin" between ②pin to ① ③pin in the shortest path. As for Cin, The withstand-voltage and allowable ripple-current ask for the selection which has a margin. (2)Output capacitor “Co” ・The ripple-current that is switching frequency flows to output-capacitor "Co".Refer to an application notebook for the way of calculating the output-ripple-current. As for Co, Use the capacitor which has low-impedance character for the switch mode power-supply . To reduce the output-ripple-noise, You must connect the output capacitor "Co" between ⑤⑥⑦pin - ①③pin at shortest. As well as the case of Cin , The withstand-voltage and allowable ripple-current ask for the selection which has a margin. (3) Output voltage setup resistor RFB ・With MPM01/04, An output voltage V o can be set up by adjusting R FB. Refer to an application noteboo k for the details. fig.10 becomes output voltage value for RFB. Connect RFB between ④pin - ①③pin at shortest. Conditions: VIN=24V , V o=12V , Io=3A, Cin=1000μF, Co=1000μF×2, RFB=200Ω fig.9 *Attention . As for a setup of V o of MPM01, 12V is an upper limit. Use MPM04 when an output voltage exceeds 12V . *Example. In case of V o=5V, RFB=510Ω In case of V o=12V, RFB=200Ω fig.10 MPM00 series Setup of the V o by RFB resistance value. 200 300 400 500 700 2000 Load
Io=3A non-isorated step-down DC/DC Converter module MPM00 Series SANKEN ELECTRIC CO., LTD. Jul/10/2013 Rev.1.0 9 http://www.sanken-ele.co.jp PCB layout recommendation (1) As for GND-line, give priority to and connect ①&③pin to the (-) side of output-capacitor Co. (2) Arrange RFB near MPM01/04, and connect a pattern to R FB at shortest as much as possible. It has the possibility that the aggravation of Line and Load regulation and a un-stable movement happen when the pattern route of RFB is long. (3) ⑧&⑨pin are terminal for switching -frequency measurement in the manufacture process. In case of use , make it electrically open. But, install LAND for the lead-pin fixation in the circuit board.

Jul/10/2013 Rev.1.0 11 http://www.sanken-ele.co.jp OPERATING PRECAUTIONS Because reliability can be affected adversely by improper storage environments and handling methods, please observe the following cautions. Cautions for Storage Ensure that storage conditions comply with the standard temperature (5 to 35 °C) and the standard relative humidity (around 40 to 75%); avoid storage locations that experience extreme changes in temperature or humidity . Avoid locations where dust or harmful gases are present and avoid direct sunlight. Reinspect for rust on leads and solderability of the products that have been stored for a long time. Cautions for Testing and Handling When tests are carried out during inspection testing and other standard test periods, protect the products from power surges from the testing d evice, shorts between the product pins, and wrong connectio ns. Ensure all test parameters are within the ratings specified by Sanken for the products. Remarks About Using Silicone Grease with a Heatsink When silicone grease is used in mounting the products on a heatsink, it shall be applied evenly and thinly . If more silicone grease than required is applied, it may produce excess stress. V olatile-type silicone greases may crack after long periods of time, resulting in reduced heat radiation effect. Silico ne greases with low consistency (hard grease) may cause cracks in the mold resin when screwing the products to a heatsink. Our recommended silicone greases for heat radiation purposes, which will not cause any adverse effect on the product life, are indicated below: Type Suppliers G746 Shin-Etsu Chemical Co., Ltd. YG6 260 Momentive Performance Materials Inc. SC10 2 Dow Corning Toray Co., Ltd. Soldering When soldering the products, please be sure to minimize the working time, within the following limits: 260 ± 5 °C 10 ± 1 s (Flow, 2 times) 380 ± 10 °C 3.5 ± 0.5 s (Soldering iron, 1 time) Soldering should be at a distance of at least 1.5 mm from the body of the products. Electrostatic Discharge When handling the products, the operator must be grounded. Groun ded wrist straps worn should have at least 1M Ω of resistance from the operator to ground to prevent shock hazard, and it should be placed near the operator. Workbenches where the products are handled should be grounded and be provided with conductive table and floor mats. When using measuring equipment such as a curve tracer, the equipment should be grounded. When soldering the products, the head of soldering irons or the sold er bath must be grounded in order to prevent leak voltages generated by them from being applied to the products. The products should always be stored and transported in Sanken shipping containers or conductive containers, or be wrapped in aluminum foil.

Application and operation examples described in this document are quoted for the sole purpose of reference for the use of the products herein and Sanken can assume no responsibility for any infringement of industrial property rights, intellectual property rights or any other rights of Sanken or any third party which may result from its use. Although Sanken undertakes to enhance the quality and reliability of its products, the occurrence of failure and defect of semiconductor products at a certain rate is inevitable. Users of Sanken products are requested to take, at their own risk, preventative measures including safety design of the equip ment or systems against any possible injury , death, fires or damages to the society due to device failure or malfunction. Sanken products listed in this document are designed and intended for the use as components in general purpose electronic equipment or apparatus (home appliances, office equipment, telecommunication equipment, measuring equipment, etc.). When considering the use of Sanken products in the applications where high er reliability is required (transportation equipment and its control systems, traffic signal control systems or equipment, fire/crime alarm systems, various safety devices, etc.), and whenever long life expectancy is required even in general purpose electronic equipment or apparatus, please contact your nearest Sanken sales represe ntative to discuss, prior to the use of the products herein. The use of Sanken products without the written consent of Sanken in the applications where extremely high reliability is required (aerospace equipment, nuclear power control systems, life support systems, etc.) is strictly prohibited. In the case that you use Sanken semiconductor products or design your products by using Sanken semiconductor products, the reliability largely depends on the degree of derating to be made to the rated values. Derating may be interpreted as a case that an operation range is set by derating the load from each rated value or surge voltage or noise is considered for derating in order to assure or improve the reliability . In general, derating factors include electric stres ses such as electric voltage, electric current, electric power etc., environmental stresses such as ambient temperature, humidity etc. and thermal stress caused due to self-heating of semiconductor products. For these stresses, instantaneous values, maximu m values and minimum values must be taken into consideration. In addition, it should be noted that since power devices or IC’s including power devices have large self -heating value, the degree of derating of junction temperature affects the reliability significantly . When using the products specified herein by either (i) combining other products or materials therewith or (ii) physically , chemically or otherwise processing or treating the products, please duly consider all possible risks that may result from all such uses in advance and proceed therewith at your own responsibility .
