具有寬輸入電壓范圍和占空比范圍的 75V 同步降壓控制器

LM5145 75V 同步降壓控制器旨在對高輸入電壓源或會發(fā)生高電壓瞬變的輸入電源軌進行電壓調(diào)節(jié)，從而更大限度地減少對外部浪涌抑制元件的需求。40ns 的高側(cè)開關(guān)最短導通時間有助于獲得較大的降壓比，支持從 48V 標稱輸入到低電壓軌的直接降壓轉(zhuǎn)換，從而降低系統(tǒng)的復雜性并減少解決方案成本。LM5145 在輸入電壓突降至 6V 時，仍能根據(jù)需要以接近 100% 的占空比繼續(xù)工作，因此是高性能工業(yè)控制、機器人、數(shù)據(jù)通信和射頻功率應用的理想選擇。\n\n強制 PWM (FPWM) 模式運行可以消除開關(guān)頻率變化以更大程度地降低 EMI，而用戶可選的二極管仿真功能則可以降低輕負載條件下的電流消耗。; ? 多功能同步降壓直流/直流控制器 \n? 6V 至 75V 的寬輸入電壓范圍\n? 具有 ±1% 反饋精度的 0.8V 基準\n? 可調(diào)輸出電壓范圍為 0.8V 至 60V\n? 40ns tON(min)，可實現(xiàn)高 VIN/VOUT 比\n? 140ns tOFF(min)，可實現(xiàn)低壓降\n? 針對 CISPR 32 要求進行了優(yōu)化\n \n? 開關(guān)頻率范圍為 100kHz 至 1MHz \n? 同步輸入和同步輸出功能\n? 可選二極管仿真或 FPWM\n \n? 適用于標準 VTH MOSFET 的 7.5V 柵極驅(qū)動器 \n? 14ns 自適應死區(qū)時間控制\n? 2.3A ;
