【IC】 同步升压DC-DC转换芯片ME2104,支持.9V低压启动,效率高达90%,静态电流低至6μA
ME2104是一款同步升压DC/DC转换器,外部使用陶瓷电容。电流模式PFM控制架构,具有输出纹波小特点。0.9V低压启动,固定输出电压,设定范围从1.8V到5.0V(±2%)。ME2104同步升压DC-DC转换芯片具有真关断功能,在CE=0V的时候,彻底切断Vbat和Vout之间的通路,防止漏电。静态功耗6μA(典型值),空载待机电流约11μA(@Vin=2V,Vout=3.3V),SOT23-5封装。

同类产品对比
ME2104 VS ME2188-N
1、待机功几乎一致
在输入2V输出3.3V的条件下,ME2104空载待机电流约11μA比ME2188-N的12μA,相差1μA左右。
2、输出电压纹波较小
ME2104输出电压纹波保持在50mV左右,ME2188-N输出纹波随着负载的加重而变大,最大可达400mV左右。
3、带载能力较弱
由于ME2104采用峰值限流模式,限流点370mA(典型值),带载能力弱于ME2188-N。
