Kev piav qhia rau TPS62147
Lub TPS62147 thiab TPS62148 yog kev ua haujlwm siab thiab yooj yim-rau-siv synchronous kauj ruam-downDC / DC converters, raws li DCS-Control™ Topology.Qhov dav input voltage ntau ntawm 3-V rau 17-V ua rau lawv haum rau ntau-cell Li-Ion aswell as 12-V intermediate mov rails.Cov cuab yeej muab 2-A txuas ntxiv tso tawm tam sim no.Lawv tsis siv neeg nkag rau Lub Hwj Chim Txuag hom ntawm lub teeb loads kom muaj kev ua haujlwm siab thoob plaws tag nrho ntau yam.Nrog rau qhov ntawd, lawv tau txais txiaj ntsig zoo rau cov ntawv thov uas xav tau kev sib txuas nrog kev ua haujlwm zoo, xws li kev lag luam PC thiab kev soj ntsuam video.Nrog rau MODE tus pin teem rau qis, qhov hloov pauv zaus tau hloov pauv raws li cov zis tam sim no thiab tseem nyob ntawm cov tswv yim thiab cov zis tawm.Cov txheej txheem no hu ua Automatic Efficiency Enhancement (AEE™) thiab tswj kev hloov pauv kev ua haujlwm siab dhau ntawm tag nrho cov haujlwm ua haujlwm.TPS62147, TPS62148 muab 1% outputvoltage raug nyob rau hauv PWM hom thiab yog li pab kom tsim ib lub hwj chim mov nrog high outputvoltage raug.FSEL tus pin tso cai rau teeb tsa qhov zaus hloov pauv hauv yuam PWM hom ntawm 1.25 MHz lossis 2.5 MHz, raws li.
Qhov feem ntau quiescent tam sim no yog 18 µA.Hauv hom kaw qhov tam sim no feem ntau yog 1µA.
Cov khoom siv muaj nyob rau hauv kev hloov kho, ntim hauv 3-mm × 2-mm VQFNpackage.
