LED Driver/Monitor

GENERAL DESCRIPTION The AD8240 LED driver/monitor, in combination with an external transistor, supplies a constant 12 V to drive LED lamps. This allows cost-effective LED lamp monitoring and short-circuit protection. The output is regulated at 12 V when the supply voltage is between 12.5 V and

LED 驅(qū)動器/監(jiān)控器

AD8240是一款LED驅(qū)動器/監(jiān)控器，與外部晶體管結(jié)合使用可提供恒定的12 V電壓，用于驅(qū)動LED燈。它可提供高性價比的LED燈監(jiān)控和短路保護。當(dāng)電源電壓介于12.5 V與27 V之間時，輸出穩(wěn)定在12 V。\n\n 可以利用CMOS兼容、電平相關(guān)的數(shù)字輸入對LED亮度進行PWM控制。當(dāng)PWM輸入為高電平時，VO開啟；當(dāng)PWM輸入為低電平時，VO關(guān)閉。AD8240的PWM設(shè)計工作頻率最高可達500 Hz，典型PWM范圍為5%至95%。\n\n LED開路檢測通過測量LED開路所引起的LED燈電流變化來實現(xiàn)。測量時使用內(nèi)部高端電流檢測放大器，可放大外部分流電 ?
