Katrangan
Kulawarga piranti TPS9260x-Q1 yaiku saluran tunggal lan dual-channel dhuwur-sisih-saiki LED
sopir.Kanthi proteksi lan diagnostik lengkap, kulawarga piranti iki darmabakti lan cocog kanggo lampu ngarep otomotif.Dasar saben pembalap independen yaiku pengontrol dorongan mode puncak-saiki.Saben pengontrol duwe rong puteran umpan balik independen, puteran umpan balik saiki kanthi shunt sensor arus dhuwur lan loop umpan balik voltase kanthi jaringan resistor-divider eksternal.Kontroler ngirimake tegangan output konstan utawa arus output konstan.Beban sing disambungake nemtokake manawa piranti kasebut ngatur arus output sing tetep (yen sirkuit tekan setpoint saiki luwih awal tinimbang set-point voltase) utawa tegangan output konstan (yen sirkuit tekan setpoint voltase tekan dhisik, contone, ing open -kahanan beban).Saben controller ndhukung kabeh topologi khas kayata boost, boost-to-baterei, SEPIC, utawa flyback. Panggunaan driver PMOS FET sisih dhuwur kanggo PWM dimming saka senar LED lan kanggo cutoff ing cilik anexternal short sirkuit kanggo GND kanggo nglindhungi sirkuit.Informasi Piranti(1)PART NUMBER SENSE-VOLTAGE
