♠ TPS61196-Q1 6-String 400-mA WLED Atekōkiri me te PWM Dimming motuhake mo ia aho
Ko te TPS61196-Q1 e whakarato ana i te otinga tino whakakotahi mo te rama LCD automotive me te mahi whakaiti PWM motuhake mo ia aho.Ko tenei taputapu he mana whakanui aratau o naianei e neke atu ana ki nga aho WLED e ono me nga rama rama maha i roto i nga raupapa.Kei ia aho he kaiwhakahaere o naianei motuhake e whakarato ana i te naianei LED ka taea te whakarite mai i te 50 mA ki te 400 mA i roto i te ± 1.5% te tika.Ko te iti o te ngaohiko i te totohu o naianei ka taea te whakarite i roto i te awhe o te 0.3 V ki te 1 V kia uru ki nga momo tautuhinga o naianei LED.Ko te awhe ngaohiko whakauru mo te taputapu mai i te 8 V ki te 30 V.
Ko te TPS61196-Q1 ka whakatika aunoa i te ngaohiko whakaputa a te kaitakawaenga whakanui ki te whakarato i te ngaohiko e hiahiatia ana e te aho LED me te hekenga ngaohiko whakamua nui rawa atu me te iti rawa o te ngaohiko e hiahiatia ana i te titi IFB o taua aho, na reira ka arotau te pai o te taraiwa.Ko tana auau whakawhiti ka whakaritea e te parenga o waho mai i te 100 kHz ki te 800 kHz.
Ko te TPS61196-Q1 e tautoko ana i te whakaheke tika PWM kanapa.Kei ia aho he whakauru mana PWM motuhake.I roto i te PWM atarua, ka whakakāhia, ka whakawetohia ranei te naianei LED i te auau me te huringa mahi e whakatauhia ana e te tohu PWM o waho.Ko te auau PWM mai i te 90 Hz ki te 22 kHz.
Ko te TPS61196-Q1 e whakauru ana i te whakamarumaru o te waa, te whakamarutanga ara-poto whakaputa, te whakamarumaru ISET poto-ki-te whenua, te whakamarumaru tuwhera me te whakamarumaru poto, te arai tuwhera me te whakamarumaru poto, me te whakamarumaru o te wera wera.I tua atu, ka taea e te TPS61196-Q1 te kite i te titi IFB poto ki te whenua hei tiaki i te aho LED.Ka whakaratohia ano hoki e te taputapu te paepae maukati i raro i te ngaohiko whakauru me te paepae whakamarumaru ngaohiko whakaputa.
