10 W恒壓/恒流充電器輕松滿足DOE-6及歐盟CoC第5版第2階段電纜末端效率標(biāo)準(zhǔn)
用于高能效電源轉(zhuǎn)換的高壓集成電路業(yè)界的領(lǐng)導(dǎo)者Power Integrations公司今日發(fā)布全新的參考設(shè)計(jì)套件RDK-420，這款10 W恒壓/恒流USB充電器基于PI公司革新性的InnoSwitch?-CH系列高集成度開關(guān)IC設(shè)計(jì)而成。InnoSwitch IC將初級側(cè)開關(guān)與初級控制器、次級控制器和反饋電路同時集成到一個符合全球安全標(biāo)準(zhǔn)的表面貼裝封裝內(nèi)。
InnoSwitch IC采用精確的次級側(cè)調(diào)節(jié)(SSR)及高速數(shù)字FluxLink?技術(shù)，越過安全隔離層傳遞直接電壓和電流測量值。這項(xiàng)新型反饋技術(shù)無需龐大的光耦器即可實(shí)現(xiàn)精確控制，同時還能避免初級側(cè)調(diào)節(jié)(PSR)固有的性能缺陷，如精確度和效率有限以及相對于空載功耗瞬態(tài)響應(yīng)較慢。其他優(yōu)勢包括：±3%恒壓、±5%恒流調(diào)節(jié);電纜壓降補(bǔ)償;可提高效率的內(nèi)置同步整流;<10 mW的空載輸入功率;以及對變壓器制造公差的適應(yīng)性。
Power Integrations產(chǎn)品營銷總監(jiān)Shyam Dujari表示：“這款參考設(shè)計(jì)展現(xiàn)了使用我們的InnoSwitch IC所能實(shí)現(xiàn)的高功率密度、高性能以及高效率。其出色的空載性能，是多家全球知名移動設(shè)備制造商在量產(chǎn)充電器時使用InnoSwitch IC的主要原因之一?！?
RDK-420現(xiàn)在可從Power Integrations進(jìn)行訂購。同時還會提供一份完整的參考設(shè)計(jì)報告(RDR-420)，內(nèi)容包括設(shè)計(jì)一款提供5 V/2 A輸出的85 VAC – 264 VAC輸入智能移動/USB充電器所需的電源規(guī)格、電路原理圖、物料清單、變壓器規(guī)格文件、印刷電路板布局以及性能數(shù)據(jù)，測量依據(jù)新的美國能源部(DOE-6)及歐盟行為準(zhǔn)則(CoC)第5版第2階段USB電纜末端效率標(biāo)準(zhǔn)。
Power Integrations (Nasdaq: POWI), the leader in high-voltage integrated circuits for energy-efficient power conversion, today announced RDK-420, a new reference design kit for a 10 W CV/CC USB charger based on the company’s revolutionary InnoSwitch?-CH family of highly integrated switcher ICs. InnoSwitch ICs combine the primary-side switch together with primary and secondary controllers and feedback circuits into a single, worldwide safety-rated, surface-mount package.
InnoSwitch ICs leverage accurate secondary-side regulation (SSR), using Power Integrations’ high-speed digital FluxLink? technology to communicate direct voltage and current measurements across the safety isolation barrier. This new feedback technique permits precise control without the need for a bulky optocoupler, while avoiding the performance compromises inherent in primary-side regulation (PSR), such as limited accuracy and efficiency and poor transient response versus no-load consumption. Other benefits include: ±3% CV, ±5% CC regulation; cable voltage-drop compensation; built-in synchronous rectification driver for high efficiency; <10 mW no-load input power; and accommodation of transformer manufacturing tolerances.
Comments Shyam Dujari, director of product marketing at Power Integrations: “This reference design shows the high power density, high performance and high efficiency that can be achieved using our InnoSwitch ICs. The excellent no-load performance is one of the key reasons why several of the world’s leading mobile device makers are already in mass production of chargers using InnoSwitch ICs.”
RDK-420 can be purchased from Power Integrations. A complete reference design report (RDR-420) is also available containing the power supply specification, schematic, bill of materials, transformer documentation, printed circuit layout and performance data required to build a 85 VAC – 264 VAC input smart mobile / USB charger with 5 V, 2 A output, measured in accordance with new US Department of Energy standards (DOE-6) and European Union Code of Conduct (CoC) Version 5, Tier 2 at the end of a USB cable.
