LM3248 | 2.5A 可調(diào)降壓-升壓射頻直流/直流轉(zhuǎn)換器 LM3248 是一款 PWM/PFM 升壓-降壓直流/直流轉(zhuǎn)換器，此轉(zhuǎn)換器在寬電壓范圍內(nèi)有效利用電池電量。 此器件架構(gòu)適用于先進(jìn)的 RF 前端系統(tǒng)，此系統(tǒng)要求動(dòng)態(tài)電壓和電流以支持運(yùn)行在 2G/3G/4G 和 3GPP/LTE 模式下的收斂式功率放大器架構(gòu)。 例如，LM3248 被設(shè)計(jì)用來(lái)在保持某些全新功耗減少 CMOS 功率放大器 (PA) 所要求的 PFM 模式的同時(shí)，產(chǎn)生更高的輸出電壓。 超快速的升壓-降壓功能減少 RF PA 系統(tǒng)開銷功率耗散，從而延長(zhǎng)了電池所支持的通話時(shí)間。 此器件將運(yùn)行在 2.7V 至 5.5V 的 VIN 電壓范圍內(nèi)，并且可在 2.5A 的最大電流負(fù)載下，在 0.4 ? 0.4V 至 4.0V（典型值）的可調(diào)輸出電壓 VOUT\n? 2.7V 至 5.5V 的輸入電壓范圍 VIN\n? 支持無(wú)縫轉(zhuǎn)換的升壓-降壓和降壓（升壓-旁路）工作模式\n? 2.5A 負(fù)載電流能力\n? 高轉(zhuǎn)換效率（典型值 >90%）\n? 具有無(wú)縫轉(zhuǎn)換的高效脈沖頻率調(diào)制 (PFM) / 脈寬調(diào)制 (PWM) 模式\n? 極快的瞬態(tài)響應(yīng)：10μs\n? ACB 減小了電感器尺寸要求\n? 抖動(dòng)以輔助接收頻帶噪聲兼容; | TI 德州儀器 | TI | |
