♠ TPS6282x 2.4-V ukuya ku-5.5-V Igalelo, 1-, 2-, 3-, 4-A Inyathelo lokuguqulela elisezantsi nge-1% yokuchaneka kwesiphumo
I-TPS6282x yindlela ekulula ukuyisebenzisa yokuchasa i-synchronous converters ye-DC-DC usapho olunomsinga ophantsi kakhulu othe cwaka we-4 μA kuphela.Ngokusekwe kwi-topology ye-DCSControl, ibonelela ngempendulo ekhawulezayo yexeshana.Isalathiso sangaphakathi sivumela ukulawula i-voltage ephumayo ukuya kuthi ga kwi-0.6 V kunye nokuchaneka okuphezulu kwe-voltage ye-1% phezu koluhlu lweqondo lokushisa eliphakathi kwe -40 ° C ukuya kwi-125 ° C.Izixhobo zentsapho ziyi-pin-topin kunye ne-BOM-to-BOM ehambelanayo.Isisombululo esipheleleyo sidinga i-inductor encinci ye-470-nH, i-capacitor ye-4.7-µF enye kunye ne-10-µF ezimbini okanye enye i-22-µF ye-capacitor yokuphuma.
I-TPS6282x ifumaneka kwiincasa ezimbini.Eyokuqala ibandakanya imowudi yogcino lwamandla engene ngokuzenzekelayo ukugcina ukusebenza kakuhle ukuya kuthi ga kwimithwalo elula kakhulu yokwandisa ixesha lebhetri lenkqubo.Owesibini uqhuba ngokunyanzeliswa kwe-PWM egcina imo eqhubekayo yokuqhuba ukuqinisekisa ubuncinci be-ripple kwi-voltage ephumayo kunye ne-quasi-fixed switching frequency.Isixhobo sibonisa i-Power Good signal kunye nesiphaluka sokuqala esithambileyo sangaphakathi.Iyakwazi ukusebenza kwimodi ye-100%.Ukukhusela impazamo, ibandakanya i-HICCUP yokukhusela isiphaluka esifutshane kunye nokuvalwa kwe-thermal.Isixhobo sifumaneka kwi-6-pin 1.5 x 1.5-mm iphakheji ye-QFN, enika isisombululo esiphezulu soxinzelelo lwamandla.
