Description
The MPM80, MPM81, and MPM82 are hybrid module ICs that include a non-isolated step-down DC / DC converter circuit with an inductor in a full-mold package. These features allow simple circuit configurations using few components, contributing to a reduction in design time and PCB space. This product can operate by simply connecting an input smoothing capacitor, an output smoothing capacitor, and output voltage setting resistors. This contributes to a reduction in man-hours for design and evaluation. Because this product contains a power inductor, the burdensome work of selecting and evaluating an inductor is unnecessary. Adoption of the free-standing full-mold package provides the design flexibility of either screwing the package to a heatsink or mounting the package directly on a PCB substrate without installing a heatsink, depending on the output voltage setting and load conditions. Features and Benefits ▪ Wide input voltage range: VIN = 8 to 30 V ▪ High efficiency: 95% (max) for MPM80, 88% (max) for MPM81, and 93% (max) for MPM82 ▪ Output voltage: 3.0 to 16 V for MPM80, 3.3 V for MPM81, and 5.0 V for MPM82 ▪ Maximum output current: IO = 2 A ▪ Operating frequency: 630 kHz ▪ Few external components required: ▫ Built-in inductor ▫ Built-in phase compensation circuit ▪ A variety of protection features include: ▫ Overcurrent (OCP) with auto restart ▫ Overvoltage (OVP) ▫ Undervoltage lockout (UVLO) ▫ Overtemperature (OTP) with auto restart

Note that output voltage setting deviation is affected by precision of the external resistors R1 and R2. For details, refer to the Application Information section. 3When the output voltage, VO , is set to any value other than 5.0 V, the inductance value and operating frequency of the built-in inductor change in direct proportion with to the setting output voltage. Therefore, the OCP operating point may vary significantly from the value when VO = 5.0 V. 4Determined by design, not tested in production.

- Place C IN and COUT as close to the MPM80 as possible.
- Connect R1, R2, and R3 from the output voltage connection point to the SGND (5th) pin.
- A switching current flows through the PGND (4th) pin along the connection between COUT and the MPM80 and therefore the common impedance of the GND loop and the switching current cause a voltage drop. Note that connecting this circuit to the GND point for output voltage detecting resistance may result in deterioration of regulation.

SANKEN ELECTRIC CO., LTD. March 11, 2013 MPM80-DS, Rev. 0.1 Cautions and Warnings
- The parallel operation to increase the current is not available.
- Thermal shutdown. The MPM01 has a thermal protection cir- cuit. This circuit keeps the IC from overheating due to overload. But this circuit cannot guarantee long-term reliability against continuously overloaded status.
- Heat radiation and reliability. The reliability of an IC is insepa- rable from the temperature in its operation. Careful consideration should be given to heat radiation and a sufficient safety margin must be allowed when designing a heatsink. When mounting the MPM01 to the heatsink, be sure to apply silicone grease and securely screw it. Please use one of the following greases we suggest: Type Suppliers G746 Shin-Etsu Chemical Co., Ltd. YG6260 Momentive Performance Materials Inc. SC102 Dow Corning Toray Co., Ltd.
- Cautions for mounting to heatsink. When the flatness around screw holes is insufficient, such as when mounting the product to the heatsink with extruded (burred) screw holes, the product can be damaged even with a lower screw torque than the recom- mended value. For mounting products, the mounting surface flatness should be 0.05 mm or less. Please select suitable screws for product shape. Do not use a flat- head machine screw because of the stress to products. A tapping screw is not recommended for the packages. When using tapping screws, a screw may enter diagonally, not vertically, depending on the conditions of hole before threading or the work situation. That may stress on the products and may cause failures. For tightening screws, if a tightening tool (such as a driver) hits the product, the package may crack, and stress, which shortens the element lifetimes and can cause the destruction, is put on internally. Tightening with an air driver makes a large impact. A screw torque higher than recommended torque can be applied and the package may be damaged. Therefore, an electric driver is recommended. When the package is secured at two or more places, tighten with the specified torque, after pre-tightening with a torque at all places. For using a driver, torque control is manda- tory.

- The contents in this document are subject to changes, for improvement and other purposes, without notice. Make sure that this is the latest revision of the document before use.
- Application and operation examples described in this document are quoted for the sole purpose of reference for the use of the prod- ucts 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 semicon- ductor 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 equipment 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 equip- ment or apparatus (home appliances, office equipment, telecommunication equipment, measuring equipment, etc.). When considering the use of Sanken products in the applications where higher 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 representative 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 requi red (aerospace equipment, nuclear power control systems, life support systems, etc.) is strictly prohibited.
- In the case that you use Sanken products or design your products by using Sanken 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 stresses 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, maximum 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 de gree 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.
- Anti radioactive ray design is not considered for the products listed herein.
- Sanken assumes no responsibility for any troubles, such as dropping products caused during transportation out of Sanken's distribu- tion network.
