Inkcazelo ye-LP8867-Q1
I-LP8867-Q1, LP8869-Q1 yimoto edityanisiweyo kakhulu, ephantsi-EMI, kulula ukuyisebenzisa umqhubi we-LED one-DC-DC converter.Isiguquli se-DC-DC sixhasa ukunyusa kunye nokusebenza kwemowudi ye-SEPIC.Isixhobo sineesinki ezine okanye ezintathu ezichanekileyo ezichanekileyo zangoku ezinokudibaniswa kwisakhono esiphezulu sangoku.
Isiguquli se-DC-DC sinolawulo lwamandla ombane oluguquguqukayo olusekwe kumbane ohamba phambili we-LED.Olu phawu lunciphisa ukusetyenziswa kwamandla ngokulungelelanisa umbane ukuya kwelona nqanaba lisezantsi ngokwaneleyo kuzo zonke iimeko.Ukunciphisa i-EMI i-DC-DC ixhasa i-spectrum yokutshintsha ukuphindaphinda kunye nongqamaniso lwangaphandle kunye nephini elizinikeleyo.Uluhlu olubanzi oluhlengahlengiswayo luvumela i-LP886x-Q1 ukunqanda ukuphazamiseka kwebhendi yefrikhwensi enovakalelo.
Uluhlu lwe-voltage yegalelo kwi-LP886x-Q1 lusuka kwi-4.5 V ukuya kwi-40 V ukuxhasa i-automotive start-stop kunye nemeko yokulahla umthwalo.I-LP886x-Q1 idibanisa iimpawu ezibanzi zokubona iimpazamo.
