♠ TPS61196-Q1 6-String 400-mA WLED Driver e nang le PWM e Ikemetseng ea Dimming Bakeng sa Khoele e 'ngoe le e 'ngoe
TPS61196-Q1 e fana ka tharollo e kopantsoeng haholo bakeng sa khanya ea morao ea LCD ea likoloi ka ts'ebetso e ikemetseng ea PWM ea dimming bakeng sa khoele ka 'ngoe. Sesebelisoa sena ke sesebelisoa sa hona joale se matlafatsang se tsamaisang likhoele tse tšeletseng tsa WLED tse nang le li-LED tse ngata ka letoto. Khoele e 'ngoe le e' ngoe e na le taolo e ikemetseng ea hajoale e fanang ka khanya ea LED e feto-fetohang ho tloha ho 50 mA ho isa ho 400 mA ka hare ho ± 1.5% ho nepahala ho ts'oanang. Matla a fokolang a sinki ea hajoale a ka hlophiseha ho tloha ho 0.3 V ho isa ho 1 V hore a lekane le litlhophiso tse fapaneng tsa hajoale tsa LED. Mofuta oa motlakase oa sesebelisoa o tsoa ho 8 V ho isa ho 30 V.
TPS61196-Q1 e fetola motlakase oa motlakase oa boost controller ka bo eona hore e fane ka motlakase o hlokoang ke thapo ea LED ka ho theoha ho hoholo ha motlakase o eang pele hammoho le bonyane ba motlakase o hlokahalang pineng ea IFB ea khoele eo, ka hona e ntlafatsa bokhoni ba mokhanni. Maqhubu a ho fetoha ha eona a hlophisitsoe ke mohanyetsi oa kantle ho tloha ho 100 kHz ho isa ho 800 kHz.
TPS61196-Q1 e ts'ehetsa ho fifala ha PWM ka kotloloho. Khoele e 'ngoe le e' ngoe e na le kenyelletso e ikemetseng ea taolo ea PWM. Nakong ea ho fifala ha PWM, motlakase oa LED oa buloa kapa oa tingoa ka nako le potoloho ea mosebetsi e khethiloeng ke lets'oao la kantle la PWM. Maqhubu a PWM a tloha ho 90 Hz ho isa ho 22 kHz.
TPS61196-Q1 e kopanya ts'ireletso ea overcurrent, ts'ireletso ea nako e khuts'oane, ts'ireletso ea nakoana ea ISET, ts'ireletso e bulehileng le e khuts'oane ea diode, ts'ireletso ea LED e bulehileng le e khuts'oane, le potoloho ea ho koala mocheso o feteletseng. Ntle le moo, TPS61196-Q1 e khona ho bona phini ea IFB e khuts'oane ho ea fatše ho sireletsa khoele ea LED. Sesebelisoa sena se boetse se fana ka "programmable input undervoltage lockout threshold and output overvoltage protection threshold.
