采用強(qiáng)制 PWM 模式的 2A 同步降壓變換器

MP2192C 是一款內(nèi)部集成功率 MOSFET 的單片降壓開(kāi)關(guān)變換器。它可在 2.5V 至 5.5V 的寬輸入電壓 (VIN) 范圍內(nèi)實(shí)現(xiàn)高達(dá) 2A 的連續(xù)輸出電流 (IOUT)，并具有出色的負(fù)載和線性調(diào)整率。其輸出電壓 (VOUT) 可調(diào)節(jié)至最低 0.6V。\n\n 該器件采用恒定導(dǎo)通時(shí)間 (COT) 控制以提供快速瞬態(tài)響應(yīng)，并使環(huán)路更易穩(wěn)定。其故障保護(hù)功能包括逐周期限流和過(guò)溫關(guān)斷保護(hù)。\n\n MP2192C 是多種應(yīng)用的理想選擇，包括高性能數(shù)字信號(hào)處理器 (DSP)、無(wú)線電源、便攜式和移動(dòng)設(shè)備以及其他低功耗系統(tǒng)。\n\n MP2192C 最大限度地減少了所 ? 強(qiáng)制脈寬調(diào)制 (PWM) 模式\n? 1.1MHz 開(kāi)關(guān)頻率 (fSW)\n? 用于上電排序的使能 (EN) 引腳\n? 1% 反饋 (FB) 精度\n? 2.5V 至 5.5V 的寬輸入工作電壓 (VIN) 范圍\n? 低至 0.6V 的可調(diào)輸出電壓 (VOUT)\n? 高達(dá) 2A 的輸出電流 (IOUT)\n? 75mΩ 和 45mΩ 內(nèi)部功率 MOSFET\n? 100% 占空比\n? 輸出放電功能\n?
