LM3535

具有環(huán)境光感應(yīng)和動態(tài)背光控制兼容性的多顯示屏 LED 驅(qū)動器; ? 驅(qū)動多達 8 個 LED，每個 LED 具有高達 25mA 的二極管電流\n? 用于實現(xiàn)動態(tài)背光控制的外部 PWM 輸入\n? 多區(qū)域環(huán)境光感應(yīng) (ALS)\n? ALS 中斷報告\n? 針對所有電流阱進行獨立的開/關(guān)控制\n? 針對 A 組（多達 6 個 LED）實現(xiàn) 128 個指數(shù)調(diào)光步進并具有 600:1 的調(diào)光比\n? 針對 B 組（多達 3 個 LED）和 D1C（1 個 LED）實現(xiàn) 8 種線性調(diào)光狀態(tài)\n? 可編程自動調(diào)光功能\n? 效率高達 90%\n? 精度為 0.55% 的電流匹配\n? 寬輸入電壓范圍（2.7V 至 5.5V）\n? 高電平有效硬件使能\n? 總解決方案尺寸 2\n? 薄型 20 引腳 DSBGA 封裝;

LM3535 器件是高度集成的 LED 驅(qū)動器，能夠驅(qū)動大型顯示屏 應(yīng)用中的 8 個并聯(lián) LED。利用獨立的 LED 控制，可以選擇 6 個主顯示屏 LED 的某個子集以用于局部照明 應(yīng)用。除一組主要 LED（共 6 個）之外，LM3535 還能夠驅(qū)動其他 2 個獨立受控的 LED 以用于指示燈 應(yīng)用。\n\nLED 驅(qū)動器電流阱分為三個獨立的受控組?？梢詫⒅饕慕M配置為驅(qū)動多達六個 LED，以用于主手機顯示屏。B 組和 C 組用于驅(qū)動輔助顯示屏、鍵盤和指示燈 LED。所有 LED 電流源都可以獨立打開和關(guān)閉，從而靈活地滿足不同應(yīng)用要求。 \n\nLM3535 可提供多區(qū)域環(huán)境光感應(yīng)功能，從而能夠在環(huán)境光條件發(fā)生變化時實現(xiàn)自主背光強度控制。還提供了 PWM 輸入，以便用戶能夠根據(jù)顯示的內(nèi)容動態(tài)調(diào)節(jié)背光強度。\n\nLM3535 能夠以 3/2 的增益或以直通模式運行電荷泵，從而無需使用電感器即可提供出色的效率。系統(tǒng)會根據(jù) LED 正向電壓選擇用于維持電流調(diào)節(jié)的正確增益，以便在輸入電壓范圍上最大程度地提高效率。\n\nLM3535 采用微型 20 引腳 0.4mm 間距薄型 DSBGA 封裝。
