具有超低 Iq 的 3V 至 65V 輸入、500mA 同步降壓轉(zhuǎn)換器

LM5166 是一款易于使用的緊湊型 3V 至 65V、超低 IQ 同步降壓轉(zhuǎn)換器，可在寬輸入電壓和負(fù)載電流范圍內(nèi)提供高效率。該器件集成有高側(cè)和低側(cè)功率金屬氧化物半導(dǎo)體場(chǎng)效應(yīng)晶體管 (MOSFET)，可提供高達(dá) 500mA 的輸出電流，輸出電壓有固定式（3.3V 或 5V）和可調(diào)節(jié)式兩種可供選擇。該轉(zhuǎn)換器設(shè)計(jì)旨在簡(jiǎn)化實(shí)現(xiàn)方案，同時(shí)優(yōu)化目標(biāo)應(yīng)用的性能。脈頻調(diào)制 (PFM) 模式可確保在輕負(fù)載條件下獲得最優(yōu)效率，恒定導(dǎo)通時(shí)間 (COT) 控制可實(shí)現(xiàn)近似恒定的工作頻率。這兩種控制方案都不需要環(huán)路補(bǔ)償，同時(shí)還能夠針對(duì)較高的降壓轉(zhuǎn)換比實(shí)現(xiàn)出色的線路和負(fù)載瞬態(tài)響應(yīng)以及短暫的脈寬調(diào)制 (PWM) 導(dǎo)通時(shí)間。 ? 3V 至 65V 寬輸入電壓范圍\n? 9.7μA 無(wú)負(fù)載靜態(tài)電流\n? –40°C 至 150°C 結(jié)溫范圍\n? 固定（3.3V、5V）或可調(diào)節(jié)輸出電壓選項(xiàng)\n? 符合 EN55022/CISPR 22 EMI 標(biāo)準(zhǔn)\n? 集成 1Ω P 溝道場(chǎng)效應(yīng)晶體管 (PFET) 降壓開(kāi)關(guān) \n? 支持 100% 占空比，可實(shí)現(xiàn)低壓降\n \n? 集成 0.5Ω N 溝道場(chǎng)效應(yīng)晶體管 (NFET) 同步整流器 \n? 無(wú)需使用外部肖特基二極管\n \n? 可編程峰值電流限制支持： \n? 500mA、300mA 或 200mA 負(fù)載\n \n? 可選 PFM 或 COT 模式工作\n? ;
