  • PW2205-2.0.pdf規格書下載

    PW2205 develops a high efficiency synchronous step-down DC-DC converter capable of delivering5A output current. PW2205 operates over a wide input voltage range from 4.5V to 30V andintegrates main switch and synchronous switch with very low RDS(ON) to minimize the conductionloss.PW2205 adopts the instant PWM architecture to achieve fast transient responses for high step downapplications and high efficiency at light loads. In addition, it operates at pseudo-constant frequencyof 500kHz under continuous conduction mode to minimize the size of inductor and Capacitor

  • 用EAGLE設計PCB電路圖

    EAGLE是功能強大而又簡單易學的電路設計軟件,它包含原理圖編輯器和印板設計編輯器及自動鋪線編輯器。首先啟動EAGLE,得到圖2界面,然后分析電路構成:555時基集成塊;4017+進制計數器;電容兩只;電阻12只;發光二極管10只。分別屬于EAGLE liner;40";Capacitor,discrecterled.Supply1。我f在設i電路之前須先打開這些元器件庫,以備調用。具體方法:在圖2控制面板的library  i'+',出 А3所示屏面。擊打相應庫的灰色小球,使之成綠色大球,這些庫的元器件就可用了。在圖2的控制面板中右擊projects,新建一個工程,取名my prject,如圖4所示。下面開始設計原理圖,先右擊myproject,隨即在觸發菜單中選擇new/schamitic,將要編輯的原理圖命名為fgdl,如圖5所示。
