超低EMI，PWM 轉(zhuǎn)恒流串聯(lián)背光

\n AW9920 是一款高效率、電感升壓型白光 LED驅(qū)動(dòng)芯片，可驅(qū)動(dòng)高達(dá) 10 顆白光 LED。內(nèi)部采用恒壓、恒流雙環(huán)路控制方式，提高了系統(tǒng)的性能及抗干擾能力。內(nèi)置過流保護(hù)、LED 開路保護(hù)及過溫保護(hù)，防止芯片進(jìn)入異常工作狀態(tài)。\n AW9920 采用 PWM 轉(zhuǎn)恒流的調(diào)光方式，極大地降低了輸出電壓及電流的紋波，避免產(chǎn)生人耳可聽見的噪聲。\n AW9920 采用獨(dú)特的 Q-Mirror TM 恒流驅(qū)動(dòng)架構(gòu)， 在 ILED 引腳電壓被外界干擾的情況下最大限度地保證輸出電流不變，有效地避免了傳統(tǒng)外置電阻架構(gòu)輸出電流隨 FB 電壓波動(dòng)發(fā)生變化的問題。\n \n?
