♠ TPS61196-Q1 6-String 400-mA WLED Direba tare da Dimming PWM Mai zaman kansa Ga Kowane Kirtani
TPS61196-Q1 yana ba da ingantaccen ingantaccen bayani don hasken baya na LCD na mota tare da aikin dimming PWM mai zaman kansa don kowane kirtani. Wannan na'urar ita ce mai sarrafa haɓaka yanayin halin yanzu tana tuƙi har zuwa igiyoyin WLED shida tare da LEDs masu yawa a cikin jerin. Kowane kirtani yana da mai sarrafa kansa na yanzu mai zaman kansa yana samar da LED na yanzu daidaitacce daga 50 mA zuwa 400 mA tsakanin ± 1.5% daidaitattun daidaito. Matsakaicin ƙarancin wutar lantarki a nutse na yanzu ana iya tsara shi a cikin kewayon 0.3 V zuwa 1 V don dacewa da saitunan LED na yanzu daban-daban. Matsakaicin ƙarfin shigar da na'urar daga 8 V zuwa 30 V.
TPS61196-Q1 yana daidaita ƙarfin fitarwa na mai sarrafa haɓaka ta atomatik don samar da kawai ƙarfin lantarki da ake buƙata ta kirtani LED tare da mafi girman ƙarfin lantarki na gaba tare da ƙaramin ƙarfin da ake buƙata a waccan fil ɗin IFB na kirtani, ta haka yana haɓaka ingantaccen direba. Ana tsara mitarta ta sauyawa ta hanyar resistor na waje daga 100 kHz zuwa 800 kHz.
TPS61196-Q1 yana goyan bayan dimming haske na PWM kai tsaye. Kowane kirtani yana da shigarwar sarrafa PWM mai zaman kansa. Yayin dimming PWM, ana kunna ko kashe LED na yanzu a mitar da zagayowar aiki waɗanda siginar PWM ta waje ta ƙayyade. Mitar PWM daga 90 Hz zuwa 22 kHz.
TPS61196-Q1 yana haɗa kariya ta wuce gona da iri, kariyar gajeriyar fitarwa, kariya ta ISET gajere zuwa ƙasa, buɗewa da gajeriyar kariyar diode, buɗewa da gajeriyar kariya ta LED, da kewayar rufewar zafin jiki. Bugu da kari, TPS61196-Q1 na iya gano guntun IFB gajere zuwa ƙasa don kare igiyar LED. Na'urar kuma tana ba da shigarwar da za a iya shigar da tsarin shigar da ƙananan ƙarfin kulle bakin kofa da mashigar kariya ta wuce gona da iri.
