CCFL背光燈及LCD對比度控制負壓控制器

MAX753/MAX754驅(qū)動冷陰極熒光燈(CCFL)并為彩色或單色LCD面板提供LCD背板偏置（對比度）電源。這些IC專為背光筆記本電腦應(yīng)用而設(shè)計。\n\n 背板偏置和CCFL電源均可獨立關(guān)斷。當兩個部分都關(guān)斷時，電源電流降至25μA。LCD對比度和CCFL亮度可通過為單獨的數(shù)字輸入提供時鐘或使用外部電位器來調(diào)節(jié)。在關(guān)斷時，LCD對比度和背光亮度設(shè)置保存在各自的計數(shù)器中。上電時，LCD對比度計數(shù)器和CCFL亮度計數(shù)器設(shè)置為半量程。\n\n 這些IC由5V穩(wěn)壓電源供電。磁性元件直接連接到電池，以充分提高電源效率。\n\n CCFL驅(qū)動器采用Royer型諧振架構(gòu)。它 ? 驅(qū)動背板和背光\n\n? 電池電壓范圍：4V至30V\n\n? 電源電流低至500μA\n\n? 以數(shù)字方式或通過電位器控制CCFL亮度和LCD偏置電壓\n\n? 負LCD對比度(MAX753)\n\n? 正LCD對比度(MAX754)\n\n? 獨立關(guān)斷背光和背板部分\n\n? 關(guān)斷電流：25μA;
