Nqe lus piav qhia rau LP8867-Q1
LP8867-Q1, LP8869-Q1 yog lub tsheb sib xyaw ua ke, qis-EMI, yooj yim-rau-siv LED tsav tsheb nrog DC-DC converter.DC-DC converter txhawb ob qho kev txhawb nqa thiab SEPIC hom kev ua haujlwm.Cov cuab yeej muaj plaub lossis peb lub dab dej tam sim no uas tuaj yeem ua ke kom muaj peev xwm ntau dua tam sim no.
Lub DC-DC converter muaj kev hloov pauv cov zis hluav taws xob tswj raws li LED rau pem hauv ntej voltages.Cov yam ntxwv no txo qis kev siv hluav taws xob los ntawm kev kho qhov hluav taws xob mus rau qib qis txaus txaus hauv txhua qhov xwm txheej.Rau EMI txo DC-DC txhawb kev sib kis spectrum rau kev hloov zaus thiab kev sib txuas sab nraud nrog rau tus pin tshwj xeeb.Qhov dav-ntau zaus hloov tau tso cai rau LP886x-Q1 kom tsis txhob muaj kev cuam tshuam rau cov zaus zaus.
Lub input voltage ntau rau LP886x-Q1 yog los ntawm 4.5 V rau 40 V los txhawb lub tsheb pib-nres thiab thauj khoom pov tseg.LP886x-Q1 suav nrog ntau yam kev ua txhaum cai.
