Inkcazelo ye-TPS630250
I-TPS63025x zisebenza kakuhle kakhulu, i-converter ephantsi ye-buck-boost yangoku ephantsi ilungele ukusetyenziswa apho i-voltage yegalelo iphezulu okanye ingaphantsi kunemveliso.Imisinga yemveliso inokuya phezulu njenge-2 A kwimowudi yokunyusa kwaye iphakame njenge-4 A kwimowudi yebhaki.Ubuninzi bomndilili wangoku kwiitshintshi bukhawulelwe kwixabiso eliqhelekileyo le-4 A. I-TPS63025x ilawula i-voltage ephumayo phezu koluhlu olupheleleyo lwe-voltage yegalelo ngokutshintshela ngokuzenzekelayo phakathi kwe-buck okanye i-boost mode ngokuxhomekeke kwi-input voltage eqinisekisa ukuguquguquka okungenamthungo phakathi kweendlela.I-buck-boost converter isekelwe kwi-frequency esisigxina, isilawuli se-pulse-width-modulation (PWM) usebenzisa ukulungiswa kwe-synchronous ukufumana ukusebenza okuphezulu.Kwimisinga yomthwalo ophantsi, isiguquli singena kwiNdlela yokuGcina amandla ukuze kugcinwe ukusebenza kakuhle kuluhlu olupheleleyo lwangoku lomthwalo.Kukho iphini yePFM/PWM evumela umsebenzisi ukuba akhethe phakathi kokusebenza kwemowudi yePFM/PWM ezenzekelayo kunye nokusebenza ngenkani kwePWM.Ngexesha lemo ye-PWM i-fixed-frequency ye-2.5 MHz isetyenziswa.I-voltage ephumayo icwangciswa ngokusebenzisa i-resistor divider yangaphandle, okanye igxininiswe ngaphakathi kwi-chip.Isiguquli sinokucinywa ukuze kuncitshiswe ukuphuma kwebhetri.Ngexesha lokuvala, umthwalo uyanqanyulwa kwibhetri.Isixhobo sifakwe kwi-package ye-WCSP ye-20-pin yokulinganisa i-1.766 mm × 2.086mm kunye ne-14-pin ye-HotRod iphakheji yokulinganisa i-2.5 mm × 3mm.
