♠ I-TPS61193 Umshayeli We-LED Osebenza Kakhulu Oneziteshi Ezintathu
I-TPS61193 iyisishayeli se-LED esisebenza kahle kakhulu, esiphansi-EMI, esisebenziseka kalula futhi esivumelana nezimo ukuze sisekele izinhlelo zokusebenza eziningi. Inamasinki amanje amathathu anembe kakhulu angahlanganiswa ukuze akwazi ukusebenza manje.
I-TPS61193 ine-DC-DC ehlanganisiwe esekela kokubili ukusebenza kwemodi ye-boost kanye ne-SEPIC. Isiguquli sinokulawulwa kwamandla kagesi okuguquguqukayo okususelwa kumandla kagesi osinki we-LED wamanje. Lesi sici sinciphisa ukusetshenziswa kwamandla ngokulungisa i-voltage ibe ileveli eyanele ephansi kuzo zonke izimo. Ukuze ulawule i-EMI isiguquli se-DC-DC sisekela i-spectrum esabalele yokushintsha imvamisa kanye nokuvumelanisa kwangaphandle nephinikhodi ezinikele.
I-TPS61193 inobubanzi obubanzi bokufaka kagesi ukusuka ku-4.5 V ukuya ku-40 V ukuze uthole ukwesekwa okuqinile kwezinhlobo ezahlukene zezinhlelo zokusebenza. I-TPS61193 ihlanganisa izici eziningi zokutholwa kwamaphutha. Idivayisi isekela ukufiphala kokukhanya kwe-PWM isilinganiso esingu-10 000:1 kufrikhwensi yokufaka ye-PWM engu-100-Hz.
