STR-V653

Low height and Creeping distance of 4mm or longer 650 V, 1.9 Ω, PWM Off-Line Switching Regulator IC STR-V653 April 25, 2013 General Descriptions Package The STR-V653 is a power IC for switching power supplies, incorporating a power MOSFET and a current mode PWM controller IC in one package. The SIP8L full mold package features low height and creeping distance of 4mm or longer between high and low voltage pin bases. To achieve low power consumption, the product includes a startup circuit and a standby function in the controller. The switching modes are automatically changed according to load conditions so that the PWM mode is in normal operation and the burst mode is in light load condition. The rich set of protection features helps to realize low component counts, and high performance-to-cost power supply.

The following design features should be observed:  The PCB traces from the D/ST pin (pin 1) should be as wide as possible, in order to enhance thermal dissipation.  In applications having a power supply specified such that V DS has large transient surge voltages, a clamp snubber circuit of a capacitor-resistor-diode (CRD) combination should be added on the primary-side winding P, or a damper snubber circuit of a capacitor (C) or a resistor-capacitor (RC) combination should be added between the D/ST pin and the S/OCP pin.

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. 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 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: Type Suppliers G746 Shin-Etsu Chemical Co., Ltd. YG6260 Momentive Performance Materials Inc. SC102 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. Grounded wrist straps worn should have at least 1MΩ 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.
