TC7660是一個(gè)引腳兼容的替代品行業(yè)標(biāo)準(zhǔn)的TC7660電荷泵電壓轉(zhuǎn)換器。它轉(zhuǎn)換為+1.5V至+10V輸入相應(yīng)的-1.5V-10V輸出，僅使用兩個(gè)低成本電容器，消除電感器和其相關(guān)的成本，尺寸和EMI。板上振蕩器工作在標(biāo)稱頻率為10kHz。低于10kHz的操作（更低的電源當(dāng)前的應(yīng)用程序）是連接外部從OSC電容接地（針1開放）。TC7660是在兩個(gè)8腳DIP和8-pin在商業(yè)和擴(kuò)展溫度的SOIC封裝范圍。TC7660包含所有必要的電路，實(shí)施高壓變頻器，兩個(gè)例外外部電容器，這可能是廉價(jià)的10MF極化電解電容器。行動(dòng)是最好的理解考慮圖2顯示了一個(gè)理想化的電壓逆變器。電容C1充電電壓，V
