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)
th auto restart
▫ Overtemperature (OTP) with
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.
Package: TO-220-8L
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.

LINE and VLOAD do not include output voltage setting deviation. 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, V , is set to any value other than 5.0 V, the inductance value and operating frequency of the built-in inductor change in
O
direct proportion with to the setting output voltage. Therefore, the OCP operating point may vary significantly from the value when VO = 5.0 V.

MPM8x Series
Thermal Derating
Figure 2 shows thermal derating curves for the MPM80. The
MPM80 requires derating based on the ambient temperature, TA ,
in use.
Use the MPM80 within the thermal derating curves shown in
figure 2. If using the MPM80 outside the curves, consider using
a heatsink. In this case, the thermal resistance, RθJ-C , between the
MPM80 junction and case is 8 °C/W. Therefore, use the MPM80
at a junction temperature, TJ , of 125°C or less, with TJ calculated
using the following procedure.
1. The internal loss, PLOSS , of the MPM80 in use is calculated as
follows:
PLOSS = ( IIN × VIN ) – ( IO × VO )
(2)
where
PLOSS is the internal loss of the MPM80, in watts,
IO is the output current of the MPM80 in amperes, and
VO is the output voltage of the MPM80, in volts.
Overall thermal resistance, RθJ-H , is determined by adding the
thermal resistances of the MPM80 and a heatsink, as follows:
RθJ-H = RθJ-C + RθH
(3)
where
RθJ-H is the thermal resistance between the MPM80 and heatsink, in degrees Celsius per watt,
RθJ-C is the thermal resistance between the MPM80 junction and
the MPM80 case, in degrees Celsius per watt, and
RθH is the thermal resistance of the heatsink, in degrees Celsius
per watt.
Junction temperature, TJ , is calculated as follows:
IIN is the input current of the MPM80, in amperes,
TJ = PLOSS × RθJ-H
VIN is the input voltage of the MPM80, in volts,
(4)
Because the maximum TJ rating of the MPM80 is 125°C, please
use the MPM80 at a junction temperature of 125°C or less.

CIN: Input capacitor
COUT: Output capacitor
R1: Output voltage setting resistor (FB to GND resistance)
R2 and R3: Output voltage setting resistors (VO to FB resistance)
• Place CIN 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.

Cautions and Warnings
• The parallel operation to increase the current is not available.
• Thermal shutdown. The MPM01 has a thermal protection circuit. 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 inseparable 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
G746
YG6260
SC102
Suppliers
Shin-Etsu Chemical Co., Ltd.
Momentive Performance Materials Inc.
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 recommended 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 flathead 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 mandatory.

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 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 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 equipment 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 required
(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 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.
• 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 distribution network.
• The contents in this document must not be transcribed or copied without Sanken's written consent.
