具 2.3A 開關(guān)電流的全功能 LED 驅(qū)動(dòng)器

LT?3518 是一個(gè)具有內(nèi)部 2.3A、45V 開關(guān)的電流模式 DC/DC 轉(zhuǎn)換器，專為驅(qū)動(dòng) LED 而設(shè)計(jì)。LT3518 起了一個(gè) LED 驅(qū)動(dòng)器的作用，可在升壓、降壓和降壓-升壓模式中運(yùn)作。它組合了一個(gè)傳統(tǒng)的電壓環(huán)路和一個(gè)獨(dú)特的電流環(huán)路，以充當(dāng)一個(gè)恒定電流源或恒定電壓源。可編程開關(guān)頻率允許針對(duì)效率或元件尺寸要求來優(yōu)化外部元件。能夠使 LT3518 的開關(guān)頻率與一個(gè)外部時(shí)鐘信號(hào)同步。可利用一個(gè) 100mV 檢測(cè)電阻器從外部設(shè)置 LED 電流。外部 PWM 輸入提供了 3000 : 1 LED 調(diào)光能力。CTRL 引腳可提供另外的 10 : 1?調(diào)光比。\n\n LT3518 采用 ? 3000 : 1 True Color PWM? 調(diào)光比 \n\n? 2.3A、45V 內(nèi)部開關(guān) \n\n? 100mV 高端電流檢測(cè) \n\n? 開路 LED 保護(hù) \n\n? 可調(diào)頻率范圍：250kHz 至 2.5MHz \n\n? 寬輸入電壓范圍：\n\n? 工作時(shí)為 3V 至 30V \n\n? 瞬變保護(hù)至 40V \n\n\n\n\n? 可工作于升壓、降壓和降壓-升壓模式 \n\n? 用于 PMOS LED 斷接的柵極驅(qū)動(dòng)器 \n\n? 恒定電流和恒定電壓調(diào)節(jié) \n\n?
