FP6166 Dual 1.5MHz, 1A Synchronous Step-Down Regulator
 
General Description
 
Download
 The FP6166 is a high efficiency current mode dual synchronous buck PWM DC-DC regulator. The internal generated 0.6V precision feedback reference voltage is designed for low output voltage. Low RDS(ON) synchronous switch dramatically reduces conduction loss. To extend battery life for portable application, 100% duty cycle is supported for low-dropout operation. Shutdown mode also helps saving the current consumption. The FP6166 is packaged in MSOP-10L(EP) and DFN-10L to reduce PCB space

FP6166双1.5MHz的,1A同步降压稳压器
 
概述
 
下载
FP6166是一个高效率电流模式双同步降压PWM DC - DC稳压。内部产生0.6V精密的 ​​反馈参考电压是专为低输出电压。低RDS(ON)同步开关,大大降低了传导损耗 。为了延长便携式应用的电池寿命,支持100%占空比低压差运行 。关断模式也有利于节省电流消耗。FP6166是采用MSOP - 10L(EP)和DFN - 10L包装,以减少PCB空间
