Communications Infrastructure Description Lub TPS54620 nyob rau hauv thermally enhanced 3.50 hli ×
3.50 hli QFN pob yog tag nrho featured 17-V, 6-A, synchronous, step-down converter uas yog optimized rau me me designs los ntawm high efficiency thiab integrating lub siab-sab thiab qis-sab MOSFETs.Ntau qhov chaw txuag tau tiav los ntawm tam sim no hom kev tswj, uas txo cov kev suav suav, thiab los ntawm kev xaiv lub siab hloov zaus, txo cov hneev taw ntawm inductor.Qhov tso zis hluav taws xob pib qhov chaw nres tsheb yog tswj los ntawm SS / TR tus pin uas tso cai rau kev ua haujlwm raws li ib qho khoom siv hluav taws xob ib leeg lossis hauv kev taug qab. xwm txheej.Lub hwj chim sequencing tseem ua tau los ntawm kev teeb tsa kom raug thiab qhib-drain fais fab pins zoo.Cycle-by-cycle tam sim no txwv nyob rau sab siab FET tiv thaiv cov cuab yeej nyob rau hauv cov xwm txheej dhau los thiab tau txhim kho los ntawm cov khoom siv qis qis uas tiv thaiv kev khiav tawm tam sim no.Kuj tseem muaj qhov qis-sab dab ntxwg nyoog tam sim no txwv uas tig tawm ntawm sab qis MOSFET txhawm rau tiv thaiv kev thim rov qab ntau dhau.Thermal shutdown disables ib feem thaum tuag kub siab tshaj thermal shutdown kub.
