Kev piav qhia rau TPS61252
Cov cuab yeej TPS61252 muab cov khoom siv hluav taws xob rau cov khoom siv los ntawm peb lub xov tooj alkaline, NiCd lossis NiMH roj teeb, lossis ib lub xov tooj ntawm tes Li-Ion lossis Li-polymer roj teeb.Qhov dav input voltage ntau yog zoo tagnrho rau lub zog portable daim ntaub ntawv xws li xov tooj ntawm tes los yog lub computer peripherals.Cov cuab yeej muaj qhov programmable resistor (RILIM) input tam sim no txwv thiab haum rau ntau yam kev siv.
Thaum lub teeb loads, lub cuab yeej cia li nkag mus hla hom (PFM), uas tso cai rau lub converter tswj qhov yuav tsum tau tso zis voltage, thaum tsuas yog kos 30 µA quiescent tam sim no los ntawm lub roj teeb.Qhov no tso cai rau qhov ua tau zoo tshaj plaws ntawm qhov qis tshaj plaws quiescent tam sim no.
TPS61252 tso cai rau siv me me inductors thiab capacitors kom ua tiav cov tshuaj me me.Qhov muaj peev xwm txo tau qhov kev txwv tam sim no los ntawm ib qho kev tiv thaiv sab nraud muaj peev xwm siv lub cev txawm tias me me inductors nrog qis qis tam sim no txhawm rau txo qis tag nrho cov kev daws teeb meem ntawm cov khoom siv hluav taws xob.Thaum lub sij hawm kaw, lub load yog kiag li disconnected ntawm lub roj teeb.TPS61252 muaj nyob rau hauv 8-pin WSON pob ntsuas 2 hli × 2 hli (DSG).
