tlhaloso e khuts'oane:

LP8867-Q1, LP8869-Q1 ke koloi e hokahaneng haholo, e tlase-EMI, e bonolo ho sebelisa mokhanni oa LED o nang le converter ea DC-DC.Mofetoleli oa DC-DC o tšehetsa ts'ebetso ea boost le SEPIC mode.Sesebelisoa se na le lisinki tse 'nè kapa tse tharo tse nepahetseng tse phahameng tse ka kopanngoang bakeng sa bokhoni bo phahameng ba hona joale.

Mofetoleli oa DC-DC o na le taolo ea motlakase ea adaptive e ipapisitseng le li-voltages tsa pele tsa LED.Tšobotsi ena e fokotsa tšebeliso ea matla ka ho fetola motlakase ho ea boemong bo tlaase ka ho fetisisa bo lekaneng maemong 'ohle.Bakeng sa phokotso ea EMI DC-DC e ts'ehetsa marang-rang a marang-rang bakeng sa ho fetoha khafetsa le khokahano ea kantle e nang le phini e inehetseng.Maqhubu a fapaneng a feto-fetohang a lumella LP886x-Q1 ho qoba tšitiso bakeng sa sehlopha sa maqhubu a bobebe.

Maqhubu a motlakase a kenang bakeng sa LP886x-Q1 a tsoa ho 4.5 V ho isa ho 40 V ho ts'ehetsa ho emisa ha likoloi le boemo ba ho lahlela thepa.LP886x-Q1 e kopanya likarolo tse ngata tsa ho lemoha liphoso.
