PowerInt公司的InnoSwitch-CH系列INN2003K器件是组合了初级,次级和反馈电路的表面安装的离线开关集成电路,包括初级FET,初级边控制器,用于同步整流的次级边控制器,采用创新的FluxLink™技术,从而不需要光耦合器.主要用在智能移动设备的充电器和适配器,LED照明Casambi CBM-001以及高效低压高电流电源.本文介绍了InnoSwitch-CH系列产品亮点和主要特性,框图,以及采用InnoSwitch-CH系列INN2003K的12W高效高功率因素智能照明电源参考设计DER612主要特性和指标,电路图,材料清单和PCB设计图.

The InnoSwitch™ Family of ICs combines primary, secondary and feedback circuits in a single surface-mounted off-line flyback switcher IC. The InnoSwitch IC incorporates the primary FET, the primary-side controller, a secondary-side controller for synchronous recTIficaTIon and an innovaTIve new FluxLink™ technology that eliminates the need for an optocoupler.

Power IntegraTIons’ FluxLink is a proprietary new communication technology that enables feedback information to be delivered across an isolation barrier without the use of any magnetic materials. FluxLink delivers a very high communication bandwidth which enables a much faster load-transient response. It is also highly reliable and does not suffer from the typical optocoupler degradation mechanisms. It is embedded into the package and by eliminating bulky optocouplers, it saves space and increases power density, which is particularly beneficial for adapters and chargers. Furthermore, this proprietary technology meets all global noise immunity standards. For safety, it complies not only with UL and TUV global isolation standards but also the more stringent CQC 5,000 meter Chinese safety standard.
