典型应用电路
FP6165 1.5MHz的,3A同步降压稳压器
FP6165是一个高效率电流模式同步降压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。FP6165是采用MSOP - 10L,DFN - 10L和SOP - 8L封装在减少PCB空间。
˙输入电压范围:2.5至5.5V ˙ ˙精密反馈参考电压:0.6V(± 2%)˙输出电流:3A(最大)˙占空比:0〜100%˙内部可调输出电压从0.6V至VIN 固定PWM频率:1.5MHz的˙低静态电流:100μA ˙无需肖特基二极管˙ ˙包装:采用MSOP - 10L(EP),DFN - 10L,SOP - 8L(EP 内置软启动˙电流模式操作˙过温保护)
FP6160 1.5MHz, 600mA Synchronous Step-Down Regulator
The FP6160B is a high efficiency current mode 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 FP6160B is packaged in SOT23-5L, and TSOT23-5L to reduce PCB space.
