♠TPS57112C-Q1 Automotive 2.95-V ukuya 6-V, 2-A, 2-MHz Buck Synchronous Converter
Isixhobo se-TPS57112C-Q1 sisixhobo esipheleleyo se-6-V, i-2-A, i-synchronous step-down mode-converter yangoku kunye nee-MOSFET ezimbini ezidibeneyo. Isixhobo se-TPS57112C-Q1 senza uyilo oluncinci ngokudibanisa i-MOSFETs, ukuphumeza ulawulo lwemowudi yangoku ukunciphisa ukubalwa kwecandelo langaphandle, ukunciphisa ubungakanani be-inductor ngokuvumela ukuya kuthi ga kwi-2-MHz yokutshintsha i-frequency, kunye nokunciphisa i-IC footprint kunye ne-3-mm × 3-mm iphakheji ye-QFN ephuculwe thermally. Isixhobo se-TPS57112C-Q1 sibonelela ngommiselo ochanekileyo kwiintlobo ezahlukeneyo zemithwalo kunye ne-± 1% ye-voltage reference (Vref) phezu kweqondo lokushisa. I-12-mΩ MOSFETs ezidityanisiweyo kunye ne-515-μA yobonelelo oluqhelekileyo lwangoku lwandisa ukusebenza kakuhle. Ukusebenzisa iphini yokuvula ukungena kwimowudi yokuvala yehlisa unikezelo lwangoku ukuya kwi-5.5 µA, eqhelekileyo. I-undervoltage lockout setting yangaphakathi yi-2.45 V, kodwa ukucwangcisa umda kunye nenethiwekhi ye-resistor kwi-pin yokuvumela kunokunyusa ukusetwa. Isikhonkwane sokuqalisa kancinci silawula irempu yokuqalisa imveliso-voltage. I-open-drain power-good signal ibonisa xa imveliso ingaphakathi kwe-93% ukuya kwi-107% yombane wayo. Ukuphinda-phinda umva kunye nokuvalwa kwe-thermal kukhusela isixhobo ngexesha lemeko ye-overcurrent.
