♠ TPS54618 2.95-V ukuya 6-V, 6-A, Synchronous Step-Down Down SWIFT™ Converter

Isixhobo se-TPS54618 sisixhobo esipheleleyo se-6-V, i-6-A, i-synchronous step-down mode yangoku-converter kunye nee-MOSFET ezimbini ezidibeneyo.

I-TPS54618 yenza uyilo oluncinci ngokudibanisa ii-MOSFETs, ukusebenzisa ulawulo lwemowudi yangoku ukunciphisa ukubalwa kwecandelo langaphandle, ukunciphisa ubungakanani be-inductor ngokuvumela ukuya kuthi ga kwi-2-MHz yokutshintsha amaza, kunye nokunciphisa i-IC footprint ngencinci, 3-mm × 3-mm. , iphakheji ye-WQFN ephuculweyo.

I-TPS54618 ibonelela ngolawulo oluchanekileyo kwiintlobo ngeentlobo zemithwalo enereferensi echanekileyo ye-±1% yombane (VREF) ngaphezulu kobushushu.

Ukusebenza kakuhle kunyuswa ngokudibeneyo i-12-mΩ MOSFETs kunye ne-515-μA eqhelekileyo yokubonelela ngoku.Usebenzisa iphini yokuvula, unikezelo lwangoku lokuvalwa luncitshiswe ukuya kwi-5.5-µA ngokungenisa imowudi yokuvala.

I-Undervoltage lockout ibekwe ngaphakathi kwi-2.6 V, kodwa inokunyuswa ngokucwangcisa umda kunye nenethiwekhi ye-resistor kwi-pin yokuvumela.I-output-voltage start-up ramp ilawulwa yipini yokuqalisa kancinci.I-open-drain power-good signal ibonisa imveliso ingaphakathi kwe-93% ukuya kwi-107% yombane wayo.

Ukuphinda-phinda umva kunye nokuvalwa kwe-thermal kukhusela isixhobo ngexesha lemeko ye-overcurrent.


  • Ngaphambili:
