UCC28780

I-Adaptive Zero Voltage switching Active-Clamp Flyback isilawuli

I-UCC28780 isilawuli se-flying-frequency esebenzayo esishwampuluzayo esinika amandla amandla amakhulu we-AC-to-DC ahambisana namazinga wokuqina womhlaba wonke anjenge-DoE Level VI ne-EU CoC V5 Tier-2. Izici zomthetho zokulawulwa ezithuthukisiwe zabasebenzisi zivumela ukusebenza ukuthi kwenziwe kahle zombili i-Silicon (Si) ne-Gallium Nitride (GaN) amandla e-FET. Ukusebenza ngqo ngamadivaysi okushintsha ahlanganisa umshayeli nama-GaN FETs kubuye kuthuthukiswe ngezimpawu zamasango ezinengqondo futhi kuvume ukuphuma.

I-Zero voltage switching (ZVS) itholakala ngaphezulu kobubanzi bokusebenza obusezingeni ngamasu athuthukile we-auto-tuning, optimization efile yesikhathi sokufa, kanye nomthetho wokulawula imvamisa oguquguqukayo. Isebenzisa isilawuli se-multimode esiguquguqukayo eshintsha ukusebenza ngokuhambisana nemibandela yokufaka nokukhipha, i-UCC28780 inika amandla okusebenza okuphezulu ngenkathi inciphisa umsindo ozwakalayo. Ngomshini oguquguqukayo oguquguqukayo ofinyelela ku-1 MHz nokuvikelwa okunamandla okungaphezu kokuhleleka, okunikezela amandla angaguquki ekwakhiweni okushisayo kulo lonke ibanga lolayini, usayizi wezinto ezifakiwe zingancishiswa futhi futhi unike amandla amandla amakhulu okuqina.

I-UCC28780 isebenza nabalawuli be-VDS-sensing synchronous rectifier isilawuli, njengeUCC24612, ukuze uzuze ukusebenza kokuguqulwa okuphezulu kakhulu kanye nemiklamo ehlangene kakhulu.

I-Zero Voltage switching egcwele neyingxenye yeZero (Primary) ye-Primary ne-Adaptive Control
Isikhathi esisehlelayo sohlelo lwangaphandle lwe-Si noma lwe-GaN
I-Frequency eshintshashintsha Okuphezulu ifinyelela ku-1 MHz
Imodi Ye-Adaptive Burst Control kanye neModi yokulinda Yokusebenza Kokulayisha Kancane Ngokukhishwa Okuphansi kanye Nokuguguleka Kwemisindo
Ukutholwa kweBrownout ngaphandle kwe-Direct Line Sensing
Ukuvikelwa Okunamandla Kwengozi Okwengezekile (i-OPP) Yokusekela Imodi Yamandla Peak
Ukuvikela Okubi: Ukushisa okuthe xaxa, ukukhipha i-Voltage engaphezulu, ukukhipha iDemo-Isekethe, Okwadlula manje, kanye nePin Fault
I-Direct Interface ene-Optocoupler based Impendulo Ivumela amandla amakhulu okukhipha
Isiqalo Esithambile Sangaphakathi
I-NTC Thermistor isikhombimsebenzisi nge Nokunikwa amandla Kwangaphandle

Zonke izimpawu zokuthengisa ziyimpahla yabanikazi bazo.
