♠ TPS61196-Q1 6-String 400-mA WLED Tsav nrog Independent PWM dimming rau txhua txoj hlua
TPS61196-Q1 muab cov kev daws teeb meem sib xyaw ua ke rau tsheb LCD backlighting nrog ib qho kev ywj pheej PWM dimming muaj nuj nqi rau txhua txoj hlua. Cov cuab yeej no yog hom tam sim no boost controller tsav mus txog rau rau WLED hlua nrog ntau LEDs hauv series. Txhua txoj hlua muaj ib qho kev ywj pheej tam sim no regulator muab lub LED tam sim no adjustable los ntawm 50 mA mus rau 400 mA nyob rau hauv ± 1.5% txuam qhov tseeb. Qhov tsawg kawg nkaus voltage ntawm lub dab dej tam sim no yog programmable nyob rau hauv thaj tsam ntawm 0.3 V rau 1 V kom haum nrog txawv LED tam sim no teeb tsa. Lub input voltage ntau rau cov cuab yeej yog los ntawm 8V txog 30V.
Lub TPS61196-Q1 kho lub boost maub los qhov tso zis voltage cia li muab qhov voltage tsuas yog xav tau los ntawm LED hlua nrog qhov loj tshaj plaws rau pem hauv ntej voltage poob ntxiv rau qhov tsawg kawg nkaus yuav tsum tau voltage ntawm txoj hlua IFB tus pin, yog li optimizing tsav tsheb efficiency. Nws hloov zaus yog programmed los ntawm ib qho kev tiv thaiv sab nraud los ntawm 100 kHz txog 800 kHz.
TPS61196-Q1 txhawb nqa ncaj qha PWM brightness dimming. Txhua txoj hlua muaj kev ywj pheej PWM tswj cov tswv yim. Thaum lub sij hawm PWM dimming, LED tam sim no yog qhib los yog tua ntawm lub zaus thiab lub luag hauj lwm voj voog uas yog txiav txim los ntawm sab nraud PWM teeb liab. PWM zaus ntawm 90 Hz txog 22 kHz.
TPS61196-Q1 integrates overcurrent tiv thaiv, output short-circuit tiv thaiv, ISET luv-rau-av tiv thaiv, diode qhib thiab luv tiv thaiv, LED qhib thiab luv tiv thaiv, thiab overtemperature shutdown circuit. Tsis tas li ntawd, TPS61196-Q1 tuaj yeem ntes IFB tus pin luv rau hauv av los tiv thaiv txoj hlua LED. Cov cuab yeej tseem muab cov programmable input undervoltage lockout pib thiab tso zis overvoltage tiv thaiv qhov pib.
