PWM Off-Line Switching Regulator ICs
Features and Benefits
Description
STR3A100 series are power ICs for switching power supplies,
incorporating a power MOSFET and a current mode PWM
• Current mode PWM control
• Built-in Random Switching function: reduces
EMI noise, simplifies EMI filters, and cuts cost by
external part reduction
• Built-in Slope Compensation function: avoids
subharmonic oscillation
• Built-in Leading Edge Blanking (LEB) function
• Auto Standby function:
controller IC in one package.
Including a startup circuit and a standby function in the
controller, the product achieves low power consumption, low
standby power, and high cost-effectiveness in power supply
systems, while reducing external components.
▫ Input power, PIN < 10 mW at no load with low power
consumption shunt regulator
The products are provided in an industry standard DIP8
package.
▫ Normal load operation: PWM switching
▫ Light load operation: Standby mode (Burst oscillation)
Applications
Switching power supplies for electronic devices such as:
• Stand-by power supply for LCD/PDP television,
desktop PC, multi-function printer, audio equipment,
and so forth
Continued on the next page…
Package: DIP8
• Small switched-mode power supply (SMPS) for printer,
BD/DVD player, set-top box, and so forth
• Auxiliary power supply for air conditioner, refrigerator,
washer, dishwasher, and so forth

Because reliability can be affected adversely by improper storage
environments and handling methods, please observe the following
cautions.
Soldering
•
When soldering the products, please be sure to minimize the
working time, within the following limits:
Cautions for Storage
260±5°C 10±1 s
(Flow, 2 times)
•
Ensure that storage conditions comply with the standard
temperature (5°C to 35°C) and the standard relative humidity
(around 40% to 75%); avoid storage locations that experience
extreme changes in temperature or humidity.
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
•
•
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.
•
When handling the products, the operator must be grounded.
Grounded wrist straps worn should have at least 1 Mꢁ 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
solder 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.
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 device, shorts between the product pins, and
wrong connections. 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.
Volatile-type silicone greases may crack after long periods of
time, resulting in reduced heat radiation effect. Silicone 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:

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 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 distribu-
tion network.
• The contents in this document must not be transcribed or copied without Sanken's written consent.
