[原创] Powerint InnoSwitch3－EP 10W双输出电源参考设计DER－745

Power Integrations公司的InnoSwitch™3-EP系列产品是离线CV/CC QR反激开关集成电路,集成了725 V/900 V MOSFET,同步整流和FluxLink反馈,从而简化反馈电源转换器的设计和制造,特别是需要高效率和/或紧凑尺寸的转换器.InnoSwitch™3-EP系列集成了多种保护特性包括线过压和欠压保护,输出过压和过流限制以及超温关断.满足EcoSmart™能量效率要求,无负载功耗小于15mW,低热损耗,隔离电压大于4000VAC,100%产品进行HIPOT测试,得到UL1577和TUV(EN60950)安全认证,应用电源高达45W,主要用在家用电器,计算机和消费类电子,以及公用表,智能电网和工业电源.本文介绍了InnoSwitch™3-EP系列产品亮点,主和次控制器框图,应用电路,以及采用InnoSwitch3-EP 900 V 的10 W双输出电源的参考设计DER-745主要特性和电指标,电路图,材料清单和变压器电路图与PCB设计图.

The InnoSwitch™3-EP family of ICs dramatically simplifies the designand manufacture of flyback power converters, particularly thoserequiring high efficiency and/or compact size. The InnoSwitch3-EPfamily combines primary and secondary controllers and safety-rated　feedback into a single IC.

InnoSwitch3-EP family devices incorporate multiple protection featuresincluding line over and undervoltage protection, output overvoltageand over-current limiting, and over-temperature shutdown. Devices areavailable with standard and peak power delivery options, andcommonly used auto-restart protection behaviors.

InnoSwitch™3-EP系列产品亮点:

Highly Integrated, Compact Footprint..
