2.5V-6V輸入電壓，1.3A升壓WLED驅(qū)動(dòng)器

MP3302是一款升壓變換器，專用于為單節(jié)鋰離子電池驅(qū)動(dòng)WLEDS陣列。MP3302 采用電流控制模式和定頻架構(gòu)來調(diào)節(jié) LED 電流，可以通過外部電流采樣電阻來檢測 LED 電流。其 200mV 的低反饋電壓降低了功率損耗，提升了轉(zhuǎn)換效率。當(dāng)由于開路出現(xiàn)過壓情況時(shí)，MP3302將被關(guān)斷。\n\n MP3302 具有輸入欠壓鎖定（UVLO）保護(hù)、限流保護(hù)和熱過載保護(hù)，當(dāng)輸出過載時(shí)可防止芯片損壞。\n\n MP3302 采用小尺寸 5引腳TSOT23封裝或8 引腳2mmx3mm QFN 封裝。 ? 內(nèi)部功率 MOSFET\n? 可驅(qū)動(dòng)多達(dá)10個(gè)串聯(lián)白光LED\n? 效率高達(dá)87%\n? 單線調(diào)光控制\n? 1.3MHz 固定開關(guān)頻率\n? 負(fù)載開路關(guān)斷\n? 200mV 低反饋電壓\n? 欠壓鎖定（UVLO）保護(hù)、過溫關(guān)斷保護(hù)\n? 1.3A內(nèi)部限流保護(hù)\n? 采用 TSOT23-5和2mm x 3mm QFN8封裝;
