4.5V至40V输入、用于汽车电子的反激/boost/SEPIC电源控制器

MAX15004A/B/MAX15005A/B是高性能、电流模式PWM控制器，可工作于4.5V至40V (抛负载)汽车级输入电压范围。如果IN自举到升压输出，启动后，输入电压可低于4.5V。该控制器集成了所有实现固定频率隔离/非隔离电源所需的控制模块。围绕MAX15004/MAX15005可以便利的设计通用boost、flyback、forward和SEPIC拓扑的变换器。\n\n 电流模式控制架构可提供优异的线路瞬态响应和逐周期限流，同时可简化频率补偿。可编程斜率补偿可进一步简化设计。60ns快速限流响应时间和低至300mV的限流门限使得控制器适用于高效、高频DC-DC变换器。该器 • 宽电源电压范围满足汽车电源要求，包括“冷启动”\n• 4.5V至40V输入电压范围(如果将输入自举到升压输出，启动后可工作在较低电压)\n\n\n\n\n• 控制电路提供优异性能并简化设计\n• 电流模式控制\n\n• 限流电压门限低至300mV，精度为5%\n\n• 可编程斜率补偿\n\n• 最大占空比为50% (MAX15004)或可调(MAX15005)\n\n\n\n\n• 高精度、同步、可调节开关频率避免干扰敏感的无线电频段\n• 开关频率可调范围：15kHz至500kHz (MAX15005A/B为1MHz)\n\n• 开关频率可通过RC设置，精度为4%;
