♠ TPS92692, TPS92692-Q1 Hoʻoponopono LED Pono Kiʻekiʻe Me ka hoʻololi ʻana i ka ʻano o nā kikoʻī.
ʻO ka TPS92692 a me ka TPS92692-Q1 nā mea hoʻoponopono kiʻekiʻe kiʻekiʻe kiʻekiʻe e pili ana i ke ʻano o kēia manawa i hoʻolālā ʻia e kākoʻo i nā topologies alakaʻi alakaʻi.Hoʻokomo ʻia ka hāmeʻa i kahi amplifier rail-to-rail no ke ana ʻana i ka LED i kēia manawa a hoʻolaha i ka ʻenehana modulation frequency spectrum no ka hoʻomaikaʻi ʻana i ka hana EMI.
Hiki i kēia mea hoʻokele LED hana kiʻekiʻe ke hoʻololi kūʻokoʻa i ka LED i kēia manawa me ka hoʻohana ʻana i nā ʻenehana dimming analog a i ʻole PWM.Loaʻa ka pane dimming analog linear me ka laulā 15: 1 ma o ka hoʻololi ʻana i ka volta ma waena o ka hoʻokomo hoʻololi analog impedance kiʻekiʻe (IADJ).Loaʻa ka PWM dimming o LED i kēia manawa ma ka hoʻololi pololei ʻana i ka pine hoʻokomo DIM/PWM me ka pōʻai hana i makemake ʻia a i ʻole ma ka ʻae ʻana i ka pōʻaiapuni PWM generator kūloko.Unuhi ka mea hana PWM i ka volta DC ma DIM/PWM pine i ke kaʻina hana e like me ka hoʻohālikelike ʻana me ka mea hana hawewe triangle kūloko.Hiki ke hoʻohana ʻia ka puka hoʻokele kaʻa puka PDRV koho e hoʻokele i kahi moʻo P-Channel MOSFET waho.
Kākoʻo nā mea TPS92692 a me TPS92692-Q1 i ka nānā ʻana i ke kūlana LED mau ma o ka puka ʻana o ka monitor (IMON).Hoʻokomo pū ʻia nā hāmeʻa i kahi puka hōʻailona hōʻailona hewa e hōʻike ai i ka overcurrent LED, overvoltage output a me nā kūlana undervoltage.
