Sharaxaada

TPS61088 waa cufnaan awood sare leh, beddele kororsi isku-dhafan oo dhammaystiran oo leh koronto 11-mΩ ah iyo beddelka 13-mΩ si ay u bixiso waxtar sare iyo xal cabbir yar oo hababka la qaadi karo ah.TPS61088 waxay leedahay koronto gelin ballaaran oo u dhexeysa 2.7 V ilaa 12 V si ay u taageerto codsiyada wata baytariyada lithium hal unug ama laba unug ah.Qalabku waxa uu leeyahay 10-A awood wareeg ah, waxana uu awood u leeyahay in uu bixiyo danab wax-soo-saarka ilaa 12.6 V. TPS61088 waxa ay isticmaashaa la-qabsiga joogtada ah ee wakhtiga ka baxsan ee kontoroolka hadda ugu sarreeya si loo habeeyo tamarta wax soo saarka.Xaaladda culeyska dhexdhexaadka ah iyo culeyska culus, TPS61088 waxay ku shaqeysaa qaab-dhismeedka cabbirka garaaca wadnaha (PWM).Xaaladda culeyska fudud, qalabku wuxuu leeyahay laba nooc oo hawlgal ah oo ay doorteen biinka MODE.
Mid waa qaabaynta soo noqnoqda garaaca wadnaha (PFM) si loo hagaajiyo waxtarka mid kalena waxaa lagu qasbay habka PWM si looga fogaado dhibaatooyinka codsiga ee ay keento inta jeer ee beddelka hooseeya.Inta jeer ee beddelka ee qaabka PWM waa la hagaajin karo, oo u dhexeeya 200 kHz ilaa 2.2 MHz by caabiyaha dibadda.TPS61088 waxa kale oo ay fulisaa hawl bilow jilicsan oo barmaamij leh iyo beddelaad la hagaajin karo ee shaqada xadka hadda ugu sarreysa.Intaa waxaa dheer, qalabku wuxuu bixiyaa 13.2-V wax soo saarka ilaalinta xad-dhaafka ah, ilaalinta xad dhaafka ah ee wareegga wareegga, iyo ilaalinta kuleylka kuleylka.TPS61088 waxaa lagu heli karaa 4.50-mm × 3.50-mm 20-pin VQFN xirmo ah.
