Lefatšeng la likarolo tsa elektronike, motlakase oa motlakase ke o mong oa tse sebelisoang ka ho fetisisa, empa IC ee e etsa eng?E fana ka potoloho e nang le motlakase o ka tsejoang esale pele le o tsitsitseng ka linako tsohle, ho sa tsotelehe motlakase o kenang.

Hore na motlakase oa motlakase o finyella mosebetsi ona joang qetellong ho itšetlehile ka moqapi.Matla a mang a motlakase a ka laoloa ke diode e bonolo ea Zener, ha lits'ebetso tse ling li hloka topology e tsoetseng pele ea li-linear kapa switching regulator.Leha ho le joalo, qetellong ea letsatsi, molaoli e mong le e mong oa motlakase o na le sepheo sa mantlha le sa bobeli:

Ea mantlha:Ho hlahisa motlakase o tsitsitseng oa potoloho ho latela ho fapana ha maemo a motlakase oa ho kenya.U kanna ua ba le 9V, empa haeba u batla feela 5V ho tsoa, u tla hloka ho e theola (Buck) ka selaoli sa motlakase.
