♠ TPS5433xA 4.5-V mpaka 28-V Zolowetsa, 3-A Output, Synchronous Step-Down DC-DC Converter
Banja la TPS5433xA la zida ndi osinthika osinthika omwe ali ndi gawo la 4.5 V mpaka 28 V. Zidazi zikuphatikizapo Chipangizochi chili ndi FET yosakanikirana yotsika kwambiri yomwe imathetsa kufunikira kwa diode yakunja yomwe imachepetsa chiwerengero cha chigawo.
Kuchita bwino kumakulitsidwa kudzera mu 128- mΩ ndi 84-mΩ MOSFETs, IQ yochepa komanso kulumpha kwapang'onopang'ono pa katundu wopepuka.Pogwiritsa ntchito pini yolumikizira, kutsekeka kwamagetsi kumachepetsedwa kukhala 2 μA.Chosinthira chotsika ichi (chiwongolero) chimapereka malamulo olondola a katundu wosiyanasiyana wokhala ndi ma voliyumu oyendetsedwa bwino omwe ndi 1.5% kuposa kutentha.
Kuchepetsa kwaposachedwa kwapakatikati pa MOSFET yam'mbali kumateteza banja la zida za TPS5433xA pamalo ochulukirachulukira ndipo kumakulitsidwa ndi malire apano omwe amalepheretsa kuthawa komwe kulipo.Njira yocheperako yocheperako imayimitsa MOSFET yotsika kuti mupewe kubweza kwanthawi yayitali.Chitetezo cha hiccup chimayambika ngati vuto la overcurrent likupitirirabe kwa nthawi yayitali kuposa nthawi yokonzedweratu.Kuzimitsa kwa kutentha kumalepheretsa chipangizocho pamene kutentha kwa kufa kumadutsa pakhomo ndikupangitsa chipangizocho kachiwiri pambuyo pa nthawi yopangira kutentha.
