♠ TPS92692, TPS92692-Q1 Isilawuli se-LED Sokunemba Okuphakeme Okune-Sread Spectrum Frequency Modulation
I-TPS92692 kanye ne-TPS92692-Q1 izilawuli ezisekelwe kumodi yamanje yesiqongo esiphezulu sokunemba eziklanyelwe ukusekela ama-top-up/down down driver topology. Idivayisi ihlanganisa i-amplifier yamanje ye-rail-to-rail ukuze ilinganise i-LED yamanje kanye nenqubo yokushintsha imvamisa ye-spectrum yokusabalalisa ukusebenza kwe-EMI okuthuthukisiwe.
Lesi silawuli se-LED esisebenza kahle singashintsha ngokuzimele i-LED yamanje sisebenzisa izindlela zokufiphalisa ze-analog noma ze-PWM. Impendulo yokufiphalisa kwe-analogi yomugqa enobubanzi obungaphezu kuka-15:1 itholwa ngokushintsha i-voltage kuwo wonke okokufaka kwe-analog impedance ephezulu (IADJ). Ukufiphala kwe-PWM yamanje ye-LED kufinyelelwa ngokulungisa ngokuqondile iphinikhodi yokufaka ye-DIM/PWM ngomjikelezo ofunekayo wemisebenzi noma ngokunika amandla isekethe yangaphakathi ye-PWM generator. Ijeneretha ye-PWM ihumusha i-voltage ye-DC kuphinikhodi ye-DIM/PWM emjikelezweni ohambisanayo womsebenzi ngokuwuqhathanisa nejeneretha yamagagasi kanxantathu wangaphakathi. Okukhiphayo ongakukhetha komshayeli wesango le-PDRV kungasetshenziswa ukushayela uchungechunge lwangaphandle lwe-P-Channel MOSFET.
Amadivayisi we-TPS92692 kanye ne-TPS92692-Q1 asekela ukuhlolwa kwesimo se-LED okuqhubekayo ngokukhishwa kwemonitha yamanje (IMON). Amadivayisi afaka nenkomba yephutha evulekile yokukhipha amanzi ukuze abonise i-LED overcurrent, ukuphuma kwamandla aphezulu kanye nezimo zokukhishwa kwe-undervoltage.
