PWM/PFM 控制器，宽输入电压范围

FAN5234 PWM控制器提供高效率和调节，具有可调输出，范围为0.9V至5.5V，用于为高性能笔记本电脑、PDA和因特网设备中的I/O、芯片组、存储器库或外设供电。 同步整流和轻载时的滞后运行为大量不同负载提供了高效率。 如果所有负载水平都要求PWM模式，滞后运行模式可被禁用。 通过使用MOSFET的RDS(ON)作为电流感测组件，能够进一步提高效率。前馈斜坡调制、平均电流模式控制以及内部反馈补偿等功能实现了负载瞬态快速响应。 FAN5234监控这些输出，并在软启动完成且输出在其设定点的±10%内时生成PGOOD（电源正常）信号。 内置过压保护可防止输出电压超过其设定点的120&# •移动系统的宽输入电压范围：2V至24V\n•卓越动态响应，使用电压前馈和平均电流模式控制\n•低端MOSFET上的无损电流感测或者使用感测电阻的精确过流\n•VCC 欠压闭锁\n•电源正常信号\n•轻载滞后模式将效率最大化\n•300KHz或600KHz运行;
