PWM Off-Line Switching Regulator ICs
Features and Benefits
Description
▪ Current mode PWM control
The STR-A6051M, STR-A6052M, STR-A6053M, and
▪ Brown-In and Brown-Out function: auto-restart, prevents
excess input current and heat rise at low input voltage
▪ Auto Standby function: improves efficiency by Burst
mode operation in light load
▫ Normal load operation: PWM mode
▫ Light load operation: Burst mode
▪ No load power consumption < 25 mW
▪ Operating frequency, fOSC(AVG)(typ) = 67 kHz
▪ Random Switching function: reduces EMI noise, and
simplifies EMI filters
▪ Slope Compensation function: avoids subharmonic
oscillation
STR-A6079M are power ICs for switching power supplies,
incorporating a power MOSFET and a current mode PWM
controller IC in one package.
To achieve low power consumption, these products include
a startup circuit and a standby function in the controller. The
switching modes are automatically changed according to load
conditions: in normal operation, PWM mode, and in light load
conditions, burst mode. The rich set of protection features
helps to realize low component counts, and high performance-
to-cost power supply.
▪ Leading Edge Blanking function

*The listed output power is based on the thermal ratings, and the peak output power can be 120% to 140% of the value stated
here. At low output voltage and short duty cycle, the output power may be less than the value stated here.
The polarity value for current specifies a sink as "+," and a source as “−,” referencing the IC.

Operating Precautions
In the case that you use Sanken products or design your prod-
ucts by using Sanken products, the reliability largely depends
on the degree of derating to be made to the rated values. Derat-
ing 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 val-
ues, 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.
• 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:

• When soldering the products, please be sure to minimize the
working time, within the following limits:
Because reliability can be affected adversely by improper stor-
age environments and handling methods, please observe the
following cautions.

Cautions for Storage
• Soldering should be at a distance of at least 1.5 mm from the
body of the products.
• Ensure that storage conditions comply with the standard tem-
perature (5 to 35°C) and the standard relative humidity (around
40 to 75%); avoid storage locations that experience extreme
changes in temperature or humidity.
Electrostatic Discharge
• When handling the products, the operator must be grounded.
Grounded wrist straps worn should have at least 1MΩ of resis-
tance from the operator to ground to prevent shock hazard, and
it should be placed near the operator.
• 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.
• Workbenches where the products are handled should be
grounded and be provided with conductive table and floor mats.
Cautions for Testing and Handling
• When using measuring equipment such as a curve tracer, the
equipment should be grounded.
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.
• When soldering the products, the head of soldering irons or
the solder bath must be grounded in order to prevent leak volt-
ages 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.
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.
