A good reference puts out a fixed voltage under varying conditions , and you can get versions that put out any of several standard voltages 一個好的參考源可以在外部變化的條件下給出固定的電壓參考,你可以使用發(fā)表過的任何標(biāo)準(zhǔn)電壓源的版本。
The hspice simulation results indicate that the charging current is up to 2a and the precision of termination voltage is very high with the error only around 10 - 3 . the efficiency is approximate 68 % when the ic is powered by fix voltage source and up to 95 % when the ic is powered by current limited source Hspice仿真結(jié)果表明,該芯片恒流模式下最大充電電流為2a ;對充電終止電壓的控制精度高達(dá)10 - 3 ;當(dāng)采用恒壓作為電源時,充電效率為68 %左右;當(dāng)采用具有電流限制功能的電源時,充電效率可達(dá)到95 % 。
