前不久我做個(gè)一個(gè)干電池給手機(jī)充電的方案,后來發(fā)現(xiàn)有很多問題.
1.由于IC沒有短路保護(hù)和OCP功能,靠輸出端加PTC來實(shí)現(xiàn),成本高,可靠度低.
2.輸出電流低,不加擴(kuò)流管3V輸入時(shí)輸出才有200-300mA,2V輸入時(shí)只有100-200mA.若加擴(kuò)流管輸出電流得不到控制,低壓特別容易燒毀管子.
3.無低壓保護(hù),輸入電壓低時(shí)干電池嚴(yán)重發(fā)熱.
4.帶負(fù)載啟動(dòng)會(huì)燒毀.
所以想請教各位大俠有沒有成本低一點(diǎn)的,帶短路保護(hù),過流保護(hù),低壓保護(hù),軟啟動(dòng)的升壓方案
謝謝!
求升壓方案
全部回復(fù)(4)
