Power Integrations公司的InnoSwitch3TM-TN系列极大地增加电器,消费类产品和工业应用辅助电源的效率.非常适合隔离和非隔离设计,这种先进的反激控制器满负载时的效率高达90%,在负载范围内具有扁平效率和非常低的无负载损耗. InnoSwitch3TM-TN系列可以用作精确的5V单输出电源,具有两个正向轨或一个正向轨和一个负向轨.器件的725V初级MOSFET,初级和次级反激控制器采用专用的FluxLink通信通路进行耦合.安全的FluxLink通信保证了可靠的同步整流和精确输出CV和CC.全面的安全特性包括输出过流保护和超温保护.小型MinSOP封装和少量外接元件使得InnoSwitch3TM-TN系列非常适合紧凑的设计.器件满足EcoSmart™能源效率,230VAC时无负载时的功耗小于5mW. 主要用在电器和工业系统的辅助电源.本文介绍了InnoSwitch3TM-TN系列产品亮点,几种电源配置案例图, 初级和次级控制器框图, HVAC应用电路:5V/1.4A和采用InnoSwitch3TM-TN系列的12W参考设计RDR-710主要特性和指标,电路图,材料清单和PCB设计图以及变压器电路图和结构图.
The InnoSwitch™3-TN family dramatically increases the efficiency of auxiliary power supplies used in appliances, consumer products and industrial applications. Ideal for both isolated and non-isolated designs, this advanced flyback controller can achieve up to 90% full load efficiency, flat efficiency across the load range and very low no-load consumption. The InnoSwitch3-TN may be used as an accurate 5 V single-output power supply, with two positive rails or with both positive and negative rails.
