♠ TPS62902, 3-V ukuya kwi-17-V, Ukusebenza okuphezulu kunye ne-Low IQ Buck Converter kwi-1.5-mm × 2-mm QFN Package
I-TPS62902 yinto esebenza kakhulu, encinci, kwaye ibhetyebhetye i-synchronous step-down DC-DC converter ekulula ukuyisebenzisa. I-frequency ekhethiweyo yokutshintsha ye-2.5 MHz okanye i-1.0 MHz ivumela ukusetyenziswa kwee-inductors ezincinci kwaye inike impendulo ekhawulezayo ngokukhawuleza. Isixhobo sixhasa ukuchaneka okuphezulu kweVOUT ye-± 1% nge-DCS-Control topology. Uluhlu olubanzi lwe-voltage ye-3-V ukuya kwi-17-V isekela iintlobo ezahlukeneyo zegama, njenge-12-V yokubonelela ngee-rails, i-single-cell okanye i-multi-cell Li-Ion, kunye ne-5-V okanye i-3.3-V yomzila.
I-TPS62902 ingangena ngokuzenzekelayo imowudi yokugcina amandla (ukuba i-auto PFM/PWM ikhethiwe) kwimithwalo elula ukugcina ukusebenza kakuhle. Ukongeza, ukubonelela ngobuchule obuphezulu kwimithwalo emincinci kakhulu, isixhobo sinomgangatho osezantsi wokuthomalalisa oqhelekileyo we-4 µA. I-AEE, ukuba yenziwe, ibonelela ngokusebenza okuphezulu kuyo yonke i-VIN, i-VOUT, kunye nomthwalo wangoku. Isixhobo sibandakanya i-S-CONF / i-MODE yokufaka i-input yokuseta isahluli sangaphakathi / sangaphandle, i-frequency switching frequency, ukukhutshwa kwe-voltage ephumayo, kunye nemodi yokugcina amandla ngokuzenzekelayo okanye ukunyanzeliswa kwe-PWM yokusebenza.
Isixhobo sifumaneka kwiphakheji encinci ye-9-pin ye-VQFN yokulinganisa i-1.50 mm × 2.00 mm kunye ne-0.5-mm pitch.
