♠ TPS61196-Q1 6-String 400-mA WLED Driver ene-PWM eZimeleyo yoDimming kumtya ngamnye
I-TPS61196-Q1 ibonelela ngesisombululo esidibeneyo sokukhanyisa i-LCD ye-automotive kunye ne-PWM dimming function ezimeleyo kumtya ngamnye. Esi sixhobo sisilawuli semowudi yangoku eqhuba ukuya kuthi ga kwiintambo ze-WLED ezintandathu ezinee-LED ezininzi kuthotho. Umtya ngamnye unomlawuli ozimeleyo okhoyo obonelela nge-LED yangoku ehlengahlengiswayo ukusuka kwi-50 mA ukuya kwi-400 mA ngaphakathi kwe-± 1.5% ukuchaneka okufanayo. I-voltage encinci kwi-sink yangoku icwangciswe kuluhlu lwe-0.3 V ukuya kwi-1 V ukuze ihambelane nemimiselo eyahlukeneyo ye-LED yangoku. Uluhlu lwegalelo lombane kwisixhobo lusuka kwi-8 V ukuya kwi-30 V.
I-TPS61196-Q1 ihlengahlengisa amandla ombane wokuphuma komlawuli ngokuzenzekelayo ukuze ibonelele kuphela amandla ombane afunwayo ngumtya we-LED kunye nowona mbane usezantsi ufunekayo kwiphini ye-IFB yomtya, ngaloo ndlela uphucula ukusebenza kakuhle komqhubi. I-frequency yayo yokutshintsha icwangciswe yi-resistor yangaphandle ukusuka kwi-100 kHz ukuya kwi-800 kHz.
I-TPS61196-Q1 ixhasa ukuqaqamba okuthe ngqo kwePWM. Umtya ngamnye unengeniso yokulawula ye-PWM ezimeleyo. Ngexesha le-PWM dimming, i-LED yangoku ivuliwe okanye ivaliwe kwi-frequency kunye ne-duty cycle egqitywe ngumqondiso we-PWM wangaphandle. Ubuninzi be-PWM buvela kwi-90 Hz ukuya kwi-22 kHz.
I-TPS61196-Q1 idibanisa ukukhuselwa kwe-overcurrent, i-output-short-circuit protection, i-ISET yokukhusela i-short-to-ground, i-diode evulekileyo kunye nokukhusela okufutshane, i-LED evulekileyo kunye nokukhusela okufutshane, kunye ne-overtemperature shutdown circuit. Ukongeza, i-TPS61196-Q1 inokubona ipini ye-IFB emfutshane ukuya emhlabeni ukukhusela umtya we-LED. Isixhobo sikwabonelela ngegalelo elinocwangciso lokutshixa umda kunye nemveliso yokhuseleko lombane.
