The PW2053 is a high-efficiency monolithic synchronous buck regulator using a constantfrequency, current mode architecture. The device is available in an adjustable version. Supply currentwith no Load is 40uA and drops to <1uA in shutdown. The 2.5V to 5.5V input voltage range makesthe PW2053 ideally suited for single Li-Ion battery powered applications. 100% duty cycle provideslow dropout operation, extending battery life in portable systems. PWM/PFM mode operationprovides very low output ripple voltage for noise sensitive applications. Switching frequency isinternally set at 1.2MHz, allowing the use of small surface mount inductors and capacitors. Lowoutput voltages are easily supported with the 0.6V feedback reference voltage

為設計高效率、低損耗的PFC電路,本文基于UCC28019進行電路設計。以UCC28019輸出的PWM波形來控制Boost升壓斬波為核心電路,使電路中的電容交替地充放電、電感交替的儲存和釋放能量,最后實現在輸入AC20V~24V電壓情況下穩定輸出DC38V。測試結果表明,系統實現效率為95%左右,電壓調整率小于1%,電源功率因數0.99。交流輸入電壓為19.0-25.8 V時,輸出直流電壓穩定性較好,電感無明顯嘯叫且紋波小,具有一定的帶負載能力和實用性。In order to design the PFC circuit with high efficiency and low loss,this paper designs the circuit based on UCC28019.The PWM waveform output by UCC28019 is used to control boost chopper as the core circuit,which alternately charges and discharges capacitors,stores and releases energy by inductors,and finally achieves stable output of DC38 V under the input voltage of AC20 V~24 V.The test results show that the system achieves about 95% efficiency,the voltage adjustment rate is less than 1%,the power factor is 0.99,and the AC input voltage is 19.0-25.8 V.The output DC voltage stability is good,the inductance has no obvious whistle and the ripple is small,so it has certain Load capacity and practicability.

全文將用一個貫穿始終的例子來說明如何繪制版圖。這個例子繪制的是一個最簡單的非門的版圖。S2-1建立版圖文件使用library manager.首先，建立一個新的庫myLib，關于建立庫的步驟，在前文介紹cdsSpice時已經說得很清楚了，就不再贅述。與前面有些不同的地方是：由于我們要建立的是一個版圖文件，因此我們在technology file選項中必須選擇compile a new tech file，或是attach to an exsiting tech file。這里由于我們要新建一個tech file，因此選擇前者。這時會彈出Load tech file的對話框，如圖2-1-1所示。在ASCII Technology File中填入csmclo0.tf即可。接著就可以建立名為inv的cel了。為了完備起見，讀者可以先建立inv的schematic view和symbol view（具體步驟前面已經介紹，其中pmos長6u，寬為0.6u。nmos長為3u，寬為0.6u。model仍然選擇hj3p和hj3n）。然后建立其layout view，其步驟為：在tool中選擇virtuoso-layout，然后點擊ok。
