♠ TPS255xx Ukuchaneka okuLungiselelayo ngoku-OkunoMda koSasazo lwaMandla
I-LM5007 0.5-A i-step-down switching converter ibonisa yonke imisebenzi efunekayo ukuphumeza umlawuli we-buck ophantsi kunye osebenzayo.Lo mguquli we-highvoltage une-80-V ehlanganisiweyo, i-0.7-A Nchannel buck switch kwaye isebenza phezu koluhlu lwegalelo lombane we-9 V ukuya ku-75 V. Isixhobo kulula ukusisebenzisa kwaye sinikezelwa kwi-8-pin VSSOP kunye ne-8-pin ephuculweyo. Iiphakheji ze-WSON.
Umguquli usebenzisa iskimu solawulo lwe-hystertic kunye ne-PWM ngexesha elichasene ngokulinganayo ne-VIN.Eli nqaku livumela i-frequency yokusebenza ukuba ihlale ingaguquguquki ngokuhambelana nomthwalo kunye nokutshintsha kombane wegalelo.Ulawulo lwe-hystertic alufuni imbuyekezo ye-loop kwaye lunikeza impendulo ekhawulezayo ngokukhawuleza.Umda wobukrelekrele wangoku uphunyezwa ngokunyanzeliswa kwexesha elichasene ne-VOUT.Esi sikimu somda sangoku siqinisekisa ukhuseleko lwesiphaluka esifutshane ngelixa sibonelela ngomthwalo ocuthiweyo wokubuyela umva.Ezinye izinto zokukhusela zibandakanya ukuvalwa kwe-thermal kunye nokubuyisela ngokuzenzekelayo, i-VCC kunye nesango lokuvala i-undervoltage lockout, kunye ne-miniter duty cycle limiter.
