LED 驅(qū)動(dòng)器，雙溝道影片/閃屏，500 mA

CAT4134 是一款大功率、雙溝道升壓轉(zhuǎn)換器，提供兩個(gè)匹配的 LED 電流。輸出電流水平由兩個(gè)電阻 RSET 或 RFLASH 控制。當(dāng) FLASH 輸入引腳為低電平（電影模式）時(shí)，RSET 設(shè)置該電流。當(dāng) FLASH 為高電平（閃屏模式）時(shí)，電阻 RFLASH 設(shè)置 LED 電流。每個(gè)溝道驅(qū)動(dòng)兩個(gè)或三個(gè)串聯(lián)的白色 LED，并提供調(diào)節(jié)電流，以控制其亮度。支持低至 3V 的輸入電源，因此該器件適用于鋰離子電池應(yīng)用。高頻率低噪聲運(yùn)行使得該器件能夠使用很小的外部電感器和陶瓷電容器，而仍然能夠保持卓越的能效。不使用時(shí)，可以通過關(guān)斷引腳將該器件置于“零”靜止模式。除了軟啟動(dòng)控制和電流限制，CAT413 ? Dual Mode (Movie or Flash) operation\n? Can drive 2, 3, 4 or 6 LEDs\n? Power efficiency up to 85%\n? Soft-start inrush current\n? Thermal shutdown protection\n? Operating temperature range -40oC to +85oC;
