方案一、(输出电压可调节,兼容CE9908):
1.低电压工作: 典型0.8V(Iout=1ma)启动
2.低的静态功耗:(开关关断状态)14uA
关断状态零工作电流
3.输出电压:3.0~5.0/5.4/5.6/6.0可根据0.1v步进订做
4.较高工作效率:90%(Typ)
输出带手机实测效率:
Vin=1.0,Vout=5~6V,Iout=200~250mA 效率80%以上
Vin=2.0,Vout=5~6v,Iout=500mA 效率80%以上
Vin=2.5,Vout=5~6v,Iout=500mA 效率85%以上
5.固定开关频率:350KHZ
7.带载能力强:
当Vin=1.0v,Vout=5~6V,Iout=300mA左右
当Vin=2~3v,Vout=5~6V,Iout=500mA左右
8.外置MOSFET
9.封装形式:SOT23-3 SOT23-5
方案二(输出电压可调节,兼容RT9266):
