安森美半導(dǎo)體全高清電視電源解決方案

摘要：本文以支持全高清的較大尺寸液晶電視為例，分析了全高清電視電源的發(fā)展趨勢(shì)，探討了旨在降低能耗、減小尺寸的架構(gòu)及技術(shù)創(chuàng)新途徑，如通過(guò)液晶顯示集成電源(LIPS)取代傳統(tǒng)的24 V逆變器電源、以及采用新穎的交錯(cuò)式PFC架構(gòu)減小輸入電流紋波支持極纖薄全高清電視的設(shè)計(jì)等。作為全球領(lǐng)先的高能效電源管理解決方案供應(yīng)商，安森美半導(dǎo)體提供高性能的電源解決方案及參考設(shè)計(jì)，幫助電子制造商縮短全高清電視產(chǎn)品的開發(fā)周期，加快上市進(jìn)程。 敘詞：全高清電視 傳統(tǒng)電源 LIPS解決方案 交錯(cuò)式PFC架構(gòu) 待機(jī)能耗 Abstract：Taking large-sized LCD TV that supports full HD as an example, this article mainly analyses the developing trends of full HDTV power, as well as discussing new architectures and innovative topologies that can help reduce power consumption and size. For example, using LIPS to replace classical 24 V inverter power supply and adopting novel interleaved PFC architecture to reduce the input current ripple to support ultra-slim full HDTV designs. As a leading global supplier of highly efficient power solutions, ON Semiconductor provides high performance power solutions and reference designs, helping electronic manufactures shorten their development cycle of full HDTV products to accelerate time-to-market.
