♠ TPS6302x Ukusebenza okuphezulu kwe-Inductor enye ye-Buck-boost Converter ene-4-A yokutshintsha
Izixhobo ze-TPS6302x zibonelela ngesisombululo sombane kwiimveliso ezixhaswe yi-alkaline yeeseli ezimbini okanye ezintathu, i-NiCd okanye i-NiMH ibhetri, i-cell-cell Li-ion okanye i-Li-polymer ibhetri, i-supercapacitors okanye ezinye iileyili zokubonelela. Imisinga yemveliso ukuya kuthi ga kwi-3 A iyaxhaswa. Xa usebenzisa iibhetri, zinokukhutshwa phantsi ukuya ngaphantsi kwe-2 V. Umguquleli we-buck-boost usekelwe kwi-frequency esisigxina, isilawuli se-pulse width modulation (PWM) usebenzisa ukulungiswa kwe-synchronous ukufumana ukusebenza kakuhle. Kwimisinga yomthwalo ophantsi, isiguquli singena kwimowudi yogcino lwamandla ukugcina ukusebenza kakuhle kuluhlu olubanzi lomthwalo wangoku. Imowudi yokugcina amandla inokukhutshazwa, ukunyanzela umguquli ukuba asebenze kwi-frequency switching frequency. Ubuninzi bomndilili wangoku kwiitshintshi bukhawulelwe kwixabiso eliqhelekileyo le-4 A. I-voltage ye-output iprogrammable usebenzisa i-resistor divider yangaphandle, okanye igxininiswe ngaphakathi kwi-chip. Isiguquli sinokucinywa ukunciphisa umjelo webhetri. Ngexesha lokuvala, umthwalo uyanqanyulwa kwibhetri.
Izixhobo ze-TPS6302x zisebenza kudederhu lobushushu bomoya osimahla obuphakathi -40°C ukuya kuma-85°C. Izixhobo zifakwe kwiphakheji ye-VSON ye-14-pin yokulinganisa i-3 mm × 4 mm (DSJ).
