可同步、高频、电流或电压模式PWM控制器，用于隔离电源

MAX8540/MAX8541脉宽调制(PWM)控制器适用于正激/反激式隔离DC-DC控制器，可为电源设计者提供更大的灵活性，并且减少外部元件的数目。这两款控制器允许使用普通的PCB布局，分别用于电流型(MAX8540)设计和电压型(MAX8541)设计。\n 两个控制器均具有200kHz至1MHz的可调开关频率和外部同步。高电平有效和低电平有效使能、欠压保护(UVP)以及过压保护(OVP)等特性减少了外部元件的数目。\n 最大占空比可调整，前馈功能能够根据输入电压调节最大占空比以限制加在变压器主线圈上最大的磁通密度。MAX8540允许用户选择斜率补偿值，以进一步优化磁元件设计。MAX8541 \n• 与外部时钟同步 \n• 可编程间隔/跨越周期或锁定模式保护 \n• 可编程欠压/过压保护 \n• 电压模式、可调斜率补偿(MAX8541) \n• 75mV至1.25mV可调电流限制减少外部元件数目 \n• 外部栅极驱动器适用于高功率应用;
