TPS65251 waxa ay leedahay saddex wax-is-weydaarsi ballaadhan oo isku-dhafan oo kala duwan oo wax-ku-beddeleyaal sare ah.Beddelayaasha waxaa loogu talagalay inay fududeeyaan codsigeeda iyadoo la siinayo naqshadeeyaha ikhtiyaarka ah inuu wanaajiyo isticmaalkooda iyadoo loo eegayo arjiga la beegsanayo.
Beddelayaashu waxay ku shaqayn karaan 5-, 9-, 12- ama 15-V system waxayna leeyihiin koronto isku dhafan.Korontada wax soo saarka waxaa lagu dejin karaa dibadda iyadoo la adeegsanayo qaybiye iska caabin ah qiima kasta oo u dhexeeya 0.8 V una dhow sahayda wax gelinta.Beddelaha kastaa wuxuu sifeeyaa biin u oggolaanaya dib u dhac ku yimaada ujeedooyinka isku xigxiga, biin bilawga jilicsan kaas oo u oggolaanaya wakhtiga bilawga jilicsan la hagaajin karo iyadoo la dooranayo capacitor-ka jilicsan, iyo biinka xadka hadda (RLIMx) kaas oo awood u siinaya naqshadeeyaha inuu hagaajiyo xadka hadda jira. adoo dooranaya iska caabin dibadeed oo wanaaji doorashada inductor.Xakamaynta qaabka hadda waxay ogolaataa magdhow RC fudud.
Inta jeer ee beddelayaashu waxay noqon karaan kuwo lagu dhejiyo iska caabin dibadeed oo ku xiran pin ROSC ama waxaa lagu dhejin karaa saacad dibadda ah oo ku xiran pin SYNC haddii loo baahdo.Nidaamiyeyaasha beddelka waxaa loogu talagalay inay ka shaqeeyaan 300 kHz ilaa 2.2 MHz.180° oo ka baxsan hawlgalka wejiga ee u dhexeeya Buck 1 iyo Buck 2, 3 (Buck 2 and 3 run in phase) waxa ay yaraynaysaa shuruudaha shaandhaynta galinta.
