♠ TPS61196-Q1 6-String 400-mA WLED Driver with Independent PWM Dimming For String ngayinye
I-TPS61196-Q1 ihlinzeka ngesisombululo esididiyelwe kakhulu sokukhanyisa ngemuva kwe-LCD yezimoto ngomsebenzi ozimele wokufiphalisa we-PWM wentambo ngayinye.Le divayisi iyisilawuli sokuthuthukisa imodi yamanje esishayela amayunithi ezinhlamvu ayisithupha e-WLED anama-LED amaningi ochungechungeni.Iyunithi yezinhlamvu ngayinye inesilawuli samanje esizimele esihlinzeka nge-LED yamanje elungisekayo ukusuka ku-50 mA ukuya ku-400 mA ngaphakathi kokunemba okufanayo okungu-±1.5%.I-voltage encane kusinki wamanje iyahleleka kububanzi obungu-0.3 V ukuya ku-1 V ukuze ilingane nezilungiselelo zamanje ze-LED ezihlukile.Ububanzi be-voltage yokufaka yedivayisi busuka ku-8 V kuye ku-30 V.
I-TPS61196-Q1 ilungisa amandla kagesi okukhiphayo wesilawuli esithuthukisiwe ngokuzenzakalelayo ukuze inikeze kuphela amandla kagesi adingwa yiyunithi yezinhlamvu ye-LED enokwehla okukhulu kakhulu kwevoltheji eya phambili kanye nenani elincane lamandla kagesi elidingekayo kuphinikhodi ye-IFB yeyunithi yezinhlamvu, ngaleyo ndlela kuthuthukisa ukusebenza kahle komshayeli.Imvamisa yokushintsha kwayo ihlelwe yi-resistor yangaphandle esuka ku-100 kHz iye ku-800 kHz.
I-TPS61196-Q1 isekela ukufiphala okuqondile kwe-PWM.Iyunithi yezinhlamvu ngayinye inokufakwayo kokulawula kwe-PWM okuzimele.Ngesikhathi sokufiphala kwe-PWM, i-LED yamanje iyavulwa noma ivalwe kumafrikhwensi nomsebenzi onqunywa isignali ye-PWM yangaphandle.Imvamisa ye-PWM isuka ku-90 Hz iye ku-22 kHz.
I-TPS61196-Q1 ihlanganisa ukuvikelwa kwe-overcurrent, ukuvikelwa kwesifunda esifushane okukhiphayo, ukuvikelwa kwe-ISET okufushane kuya phansi, ukuvikelwa okuvulekile kwe-diode nokufushane, ukuvikelwa kwe-LED okuvulekile nokufushane, nomjikelezo wokuvala izinga lokushisa elingaphezulu.Ngaphezu kwalokho, i-TPS61196-Q1 ingathola iphinikhodi ye-IFB imfushane ukuya phansi ukuze ivikele intambo ye-LED.Idivayisi iphinde inikeze umkhawulo wokukhiya we-undervoltage ohlelelekayo kanye nomkhawulo wokuvikela u-overvoltage.
