Power Integrations Introduces New Power Supply wafer. The EU and the United States will soon release a new energy efficiency standards, and is expected to continue on the road in 2016; the power transformer to assist designers of mobile devices easier to meet the relevant regulatory requirements, consistent with mobile device charger adapter towards the development of high power density trend, Power Integrations launched the active components on the primary side, the secondary side feedback circuitry and integrated in the same package of high-performance, highly integrated solutions, innovative mobile devices is expected to power supply design.

Power Integrations business development director, said Shyam Dujari, InnoSwitch is currently available on most integrated power supply converter chip, and in line with the United States, the European Union recently proposed energy efficiency standards for external power supply.
Bauer business development director Shyam Dujari Intel said that the EU Code of Conduct external power efficiency fifth edition of the draft --CoC V5, the external power supply have different performance requirements at different load conditions to ensure power efficiency. The specification of the first phase took effect January 1, 2014, the second phase is expected to be on the road January 1, 2016.
Coincidentally, the US Department of Energy (DOE) has released this final rule an external power supply; regulations require an external power supply current minimum energy efficiency required in one fell swoop from Level 4 to Level 6. This energy efficiency standards in federal legislation (Federal Register) journal published two years later, that is to take effect Feb. 10, 2016, will bring new challenges to the power supply design of mobile devices.
In addition to the new regulations is to promote the power supply must be the driving factor in device performance improvement, the trend toward large-scale development of mobile devices is also important thrust. Dujari explained that the large size of smart phones, tablet PCs so that the battery capacity is increased, but the adapter has not subsequently increase the size of the design, which represents the adapter, charger Power density must be rising, in order to meet mobile device power supply needs.
In response to these challenges, Power Integrations in 2014 in Munich Electronics Show (Electronica) officially released a new power supply chip --InnoSwitch. The product integrates the primary side field effect transistor (FET), lossless current sensing (Lossless Current Sense), early / secondary-side controller synchronous rectification (SR) controller and other components, and have a high-speed Intel Bauer digital FluxLink technology, security across the isolation barrier, highly accurate secondary-side direct voltage and current measurements communications; and combined with synchronous rectification and primary-side controller, plus FluxLink technology, making the synchronous rectifier switch timing can be optimized to improve power supply efficiency.
In addition, InnoSwitch provides up to 25 watts (W), constant voltage and constant current, and therefore suitable for smart mobile device chargers and converters, also widely used in set-top boxes, network equipment and computer peripheral equipment.
Dujari stressed, InnoSwitch see is the industry's first integrated on the same silicon-based panel of the highest degree of power supply solutions that can reduce the amount of components using the power supply, followed by second-stage regulator architecture allows designers to use a simpler, more cost-transformer, while improving production yields, thereby significantly reduce manufacturing costs and improve the efficiency of the power supply. Currently there are two mobile device manufacturers are using a combination of FluxLink technology InnoSwitch series IC to produce charger.
