MAX5021

电流模式PWM控制器,用于隔离型电源

MAX5021/MAX5022电流模式PWM控制器包含宽输入电压范围隔离电源设计所需的所有控制电路。这些器件非常适合用于通用输入(85VAC至265VAC)离线或电信(-36VDC至-72VDC)电源。\n\n 欠压闭锁(UVLO)电路具有较大迟滞,加上启动和工作电流低,可降低启动电阻中的功耗,并支持使用陶瓷旁路电容。262kHz开关频率在内部调整为}12%精度;这为优化磁性和滤波器元件创造了条件,有助于实现紧凑、高性价比的电源。对于正向转换器和反激式转换器,分别推荐使用MAX5021(最大占空比为50%)和MAX5022(最大占空比为75%)。MAX5021 • 采用小型6引脚SOT23封装\n\n• 启动电流:50µA(典型值)\n\n• 工作电流:1.2mA(典型值)\n\n• UVLO迟滞高达14V\n\n• 固定开关频率:262kHz ±12%\n\n• 50%最大占空比限制(MAX5021)\n\n• 75%最大占空比限制(MAX5022)\n\n• 60ns逐周期限流响应时间;
