200KHz, 55V, 2A LED驅(qū)動(dòng)器

MP2488MP2488是一款固定頻率降壓型開(kāi)關(guān)穩(wěn)壓器，可為大功率LED提供高達(dá)2A的恒定電流。它集成了上管高壓功率MOSFET，具有3.2A的限流值。其4.5V 至 55V 的寬工作輸入電壓范圍使其適用于各種降壓應(yīng)用，包括汽車、工業(yè)和普通照明應(yīng)用。MP2488采用峰值電流控制模式和200mV基準(zhǔn)電壓，可實(shí)現(xiàn)快速環(huán)路響應(yīng)、輕松補(bǔ)償和精確的LED電流調(diào)節(jié)。其開(kāi)關(guān)頻率可通過(guò)一個(gè)高達(dá)200kHz的外部電阻器設(shè)置，可避免EMI（電磁干擾）噪聲問(wèn)題。MP2488還提供過(guò)溫關(guān)斷保護(hù)功能，以實(shí)現(xiàn)穩(wěn)定可靠的操作。關(guān)斷模式下其靜態(tài)電流為12μA，因此也適用于電池供電應(yīng)用。MP2488 采用小尺寸 10引腳3mm ? 寬工作輸入電壓范圍：4.5V 至 55V\n? 220m? 內(nèi)部功率 MOSFET\n? 高達(dá) 200kHz 可調(diào)開(kāi)關(guān)頻率\n? 130μA 靜態(tài)電流\n? 采用陶瓷電容器可穩(wěn)定工作\n? 內(nèi)部軟啟動(dòng)\n? 效率高達(dá)97.5%\n? 200mV基準(zhǔn)電壓以實(shí)現(xiàn)高效率\n? 采用10引腳3mmx3mm QFN 封裝和帶散熱焊盤的SOIC8封裝;
