概述

G5175设备具有三个同步5.5V输入范围的高效降压转换器。转换器的设计是为了简化其应用程序，同时让设计者可以根据目标应用程序优化其使用。

转换器可以在5V系统中工作，并具有集成功率晶体管。输出电压可以使用电阻分压器从外部设置为1.0V和接近输入电源之间的任何值。每个转换器都具有启用引脚，允许出于排-序目的延迟启动，软启动引脚允许通过选择软启动电容器来调整软启动时间。电流模式控制允许简单的RC补偿。

转换器的开关频率可以操作1MHz。

G5175具有一个监控电路，用于监控每个转换器的输出。一旦完成测序，PGOOD引脚被断言，所有PG信号被报告，并且可选择的复位时间结束。PGOOD信号的极性是有-效的高电平。

G5175 Buck1还具有轻负载脉冲跳跃模式，PSM模式允许在主机处理器处于待机（低活动）模式时减少提供给系统的输入功率。
