可同步、高頻、電流或電壓模式PWM控制器，用于隔離電源

MAX8540/MAX8541脈寬調(diào)制(PWM)控制器適用于正激/反激式隔離DC-DC控制器，可為電源設(shè)計者提供更大的靈活性，并且減少外部元件的數(shù)目。這兩款控制器允許使用普通的PCB布局，分別用于電流型(MAX8540)設(shè)計和電壓型(MAX8541)設(shè)計。\n 兩個控制器均具有200kHz至1MHz的可調(diào)開關(guān)頻率和外部同步。高電平有效和低電平有效使能、欠壓保護(UVP)以及過壓保護(OVP)等特性減少了外部元件的數(shù)目。\n 最大占空比可調(diào)整，前饋功能能夠根據(jù)輸入電壓調(diào)節(jié)最大占空比以限制加在變壓器主線圈上最大的磁通密度。MAX8540允許用戶選擇斜率補償值，以進一步優(yōu)化磁元件設(shè)計。MAX8541 \n? 與外部時鐘同步 \n? 可編程間隔/跨越周期或鎖定模式保護 \n? 可編程欠壓/過壓保護 \n? 電壓模式、可調(diào)斜率補償(MAX8541) \n? 75mV至1.25mV可調(diào)電流限制減少外部元件數(shù)目 \n? 外部柵極驅(qū)動器適用于高功率應(yīng)用;
