Kev piav qhia
TPS9260x-Q1 tsev neeg ntawm cov khoom siv yog ib qho channel thiab dual-channel siab-sab-tam sim no LED
tus tsav tsheb.Nrog kev tiv thaiv tag nrho thiab kev kuaj mob, tsev neeg ntawm cov cuab yeej no tau mob siab rau thiab ua kom haum rau lub tsheb pem hauv ntej teeb pom kev zoo.Lub hauv paus ntawm txhua tus neeg tsav tsheb ywj pheej yog lub ncov-tam sim no-hom boost controller.Txhua tus maub los muaj ob txoj kev tawm tswv yim ywj pheej, lub voj voog tawm tswv yim tam sim no nrog rau qhov siab tam sim no-sensing shunt thiab lub voj voog tawm tswv yim nrog rau sab nraud resistor-divider network.Tus maub los muab qhov tso zis tsis tu ncua lossis qhov tso zis tsis tu ncua tam sim no.Kev sib txuas ntawm kev sib txuas txiav txim siab seb lub cuab yeej tswj hwm qhov kev tso tawm tsis tu ncua (yog tias lub voj voog mus txog qhov chaw teeb tsa tam sim no ntxov dua li qhov ntsuas hluav taws xob) lossis qhov hluav taws xob tsis tu ncua (yog tias lub Circuit Court ncav cuag qhov ntsuas hluav taws xob ua ntej, piv txwv li, hauv qhov qhib. -load condition).Txhua tus maub los txhawb nqa txhua yam khoom siv xws li boost, boost-to-battery, SEPIC, lossis flyback.Siv lub siab-sab PMOS FET tsav tsheb yog rau PWM dimming ntawm txoj hlua LED thiab rau kev txiav tawm nyob rau hauv cov ntaub ntawv ntawm anexternal luv. Circuit Court rau GND los tiv thaiv Circuit Court.Device Information(1)PART NUMBER SENSE-VOLTAGE
