♠ TPS54388C-Q1 Automotive 2.95-V ukuya 6-V, 3-A , 2-MHz Buck Synchronous Converter
Isixhobo se-TPS54388C-Q1 sisixhobo esipheleleyo se-6-V, i-3-A, i-synchronous step-down mode-converter yangoku kunye nee-MOSFET ezimbini ezidibeneyo.
Isixhobo se-TPS54388C-Q1 senza uyilo oluncinci ngokudibanisa i-MOSFETs, ukuphumeza ulawulo lwemowudi yangoku ukunciphisa ukubalwa kwamacandelo angaphandle, ukunciphisa ubungakanani be-inductor ngokuvumela ukuya kuthi ga kwi-2-MHz yokutshintsha i-frequency, kunye nokunciphisa i-IC footprint nge-3-mm × 3-mm iphakheji ye-QFN ephuculwe thermally.
Isixhobo se-TPS54388C-Q1 sibonelela ngommiselo ochanekileyo kwiintlobo ezahlukeneyo zemithwalo ene-± 1% yereferensi ye-voltage echanekileyo (Vref) phezu kweqondo lokushisa.
I-12-mΩ MOSFETs ezidityanisiweyo kunye ne-515-μA yobonelelo oluqhelekileyo lwangoku lwandisa ukusebenza kakuhle. Ukufaka imowudi yokuvala usebenzisa iphini yokuvula kunciphisa unikezelo lokuvalwa lokuvalwa ukuya kwi-5.5 µA, eqhelekileyo.
Isicwangciso sokutshixa se-undervoltage sangaphakathi sikwi-2.45 V, kodwa ukucwangcisa umda kunye nenethiwekhi ye-resistor kwi-pin yokuvumela kunokunyusa ukusetha. Isikhonkwane esicothayo siseta 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.
