I-UCC28780

I-Adaptive Zero Voltage Ukutshintsha isilwanyana esisebenzayo seCamp Flyback

I-UCC28780 lulawulo olusebenza rhoqo lwe-clamp flyback elwenza ukuba amandla aphezulu e-AC ukuya kwi-DC athobele imigangatho yokusebenza ngokugqibeleleyo yehlabathi njenge-DoE Level VI kunye ne-EU CoC V5 Tier-2. Iimpawu zomthetho zolawulo zomsebenzisi eziqhubekekayo zivumela intsebenzo ukuba yenziwe yenziwe zombini iiSilicon (Si) kunye neGallium Nitride (GaN) iiFET zamandla. Ukusebenza ngokuthe ngqo nezixhobo ezitshintshayo ezidibanisa umqhubi kunye neeGaNF zeeNgcali zongezwa ngakumbi ngemigangatho yamanqanaba esango kunye nokwenza iziphumo.

Ukutshintshwa kwevolve switching (i-ZS) kufezekiswa kudweliso olubanzi lokusebenzisa ubuchwepheshe obuphambili bokwenza ubuchwepheshe, ukwenziwa kwexesha lokuguqula ixesha, kunye nomthetho wokutshintsha ohamba rhoqo. Usebenzisa ulawulo lwemultimode eguqukayo etshintsha ukusebenza ngokusekwe kwiimeko zokufakelwa kunye nokungenayo, i-UCC28780 yenza ubuchule obuphezulu ngelixa kuncitshiswa ingxolo evakalayo. Ngotshintsho oluguqukayo oluhamba rhoqo ukuya kuthi ga kwi-1 MHz kunye nokukhuseleka ngokuchanekileyo kwamandla okunika amandla, nto leyo ibonelela njengamandla eguquguqukayo yoyilo olushushu kwimigangatho ebanzi yomda, ubungakanani bezinto ezifikayo zinokuncitshiswa ngakumbi kwaye zenze ukuba amandla aphezulu abe namandla.

I-UCC28780 isebenza kunye nabalawuli be-VDS-sensing synchronous rectifier controlers, njengeI-UCC24612, ukufezekisa ukusebenza ngokuguqukayo okuphezulu kunye noyilo olubumbeneyo.

Ukutshintsha okuguqukayo kunye nokuguqukayo kweZero Voltage (ZVS) yePrayimari eyiPrayimari ngoLawulo lweAdaptive
Ixesha elicwangcisiweyo loHlelo lwangaphandle lwe-Si okanye lwee-FET
Ukutshintsha okuphezulu rhoqo ukuya kwi-1 MHz
Ulawulo lweAdaptive Burst Management kunye neMowby yokulinda eKhanyayo yoMthwalo oLula kunye nokuPhumela okuNcinci kunye nokuPhungulwa kwengxolo
Ukufunyanwa kweBrownout ngaphandle kokwenziwa kolayini ngqo
Ukhuseleko oluCwangcisiweyo olugqithisela amandla agcweleyo (i-OPP) yokuXhasa indlela yeMandla ePhezulu
Ukukhuselwa okungalunganga: Ubushushu obugqithisileyo, ukuvelisa ngaphezulu kweVolthi, ukuPhuma okuSekethe-Circuit, ukugqithisa okwangoku, kunye nePine phoso
Ukudibana ngokuthe ngqo kunye neOptocoupler esekwe Impendulo ivumela amandla aMandla eSiphumo seMpembelelo
UkuQalwa kweSoftware yangaphakathi
I-NTC Thermistor Isinxibelelanisi kunye Nangaphandle Yenza amandla

Zonke iimpawu zentengiso ziyipropathi yabanini bazo.
