用于主、次顯示屏的高效率、26V、升壓型轉(zhuǎn)換器，用于OLED和/或白光LED

MAX8608Y/MAX8608Z雙路LED驅(qū)動器采用一個電感即可為雙屏蜂窩電話中的有機LED (OLED)電源或者白光LED (WLED)驅(qū)動提供兩路輸出。每路輸出均可針對OLED配置為電壓調(diào)節(jié)方式(最高可調(diào)至26V)，或者針對WLED配置為電流調(diào)節(jié)方式(最大可調(diào)至40mA)。\n 該拓撲結(jié)構(gòu)中集成了一個1MHz/500kHz PWM升壓轉(zhuǎn)換器和兩個輸出負載開關(guān)，從而可極大地降低尺寸、減少外部元件數(shù)量和提高效率。每路輸出(OUTA，OUTB)直接通過單獨的邏輯輸入進行控制；但如果ENA為高電平，則忽略ENB的使能信號并關(guān)閉OUTB。單路CTRL輸入可接受模擬或者直接PWM亮度控制信號，以便均 \n? 支持雙屏 OLED + OLED 白光LED + OLED 白光LED + 白光LED \n? 兩路輸出共享一個電感和一個肖特基二極管 \n? 輸出True Shutdown? \n? 輸出13V至20V/10mA至20mA時，效率超過83% \n? 高達900mW的輸出功率 \n? 靈活的模擬或者PWM亮度控制 \n? 可選擇1MHz或者500kHz PWM工作頻率 \n? 溫度降額功能(MAX8608Y) \n? 小尺寸外部元件 \n? 26V輸出過壓保護 \n? 專為低輸入/輸出波紋而優(yōu)化 \n? 軟啟動消除了浪涌電流;
