♠ TPS61193 High-Performance Three-Channel LED Driver
TPS61193 ke mokhanni oa LED o sebetsang hantle haholo, o tlase-EMI, o bonolo ho sebelisa mokhanni oa LED o nang le bonolo ho ts'ehetsa mefuta e mengata ea lits'ebetso. E na le lisinki tse tharo tse nepahetseng haholo tsa hona joale tse ka kopanngoang bakeng sa bokhoni bo phahameng ba hona joale.
TPS61193 e na le DC-DC e kopaneng e ts'ehetsang ts'ebetso ea boost le SEPIC mode. Mofetoleli o na le taolo ea motlakase ea adaptive e ipapisitseng le li-voltages tsa li-headroom tsa sink tsa LED hajoale. Karolo ena e fokotsa tšebeliso ea matla ka ho fetola motlakase hore o be boemong bo tlase bo lekaneng maemong 'ohle. Bakeng sa taolo ea EMI, converter ea DC-DC e ts'ehetsa marang-rang a ho fetola maqhubu le khokahano ea kantle e nang le phini e inehetseng.
TPS61193 e na le mefuta e mengata ea matla a ho kenya letsoho ho tloha ho 4.5 V ho isa ho 40 V bakeng sa tšehetso e matla ea mefuta e fapaneng ea lits'ebetso. TPS61193 e kopanya likarolo tse ngata tsa ho lemoha liphoso. Sesebelisoa se ts'ehetsa karo-karolelano ea khanya ea PWM ea 10 000: 1 bakeng sa maqhubu a 100-Hz a kenyelletso ea PWM.
