Inkcazelo ye-TPS54335A
Intsapho ye-TPS5433xA yezixhobo ziguquli ze-synchronous kunye ne-input-voltage range ye-4.5 ukuya kwi-28 V. Ezi zixhobo ziquka i-FET edibeneyo yokutshintsha kwe-FET ekhupha imfuno ye-diode yangaphandle enciphisa ukubalwa kwamacandelo.
Ukusebenza kakuhle kunyuswa ngokudibeneyo i-128-mΩ kunye ne-84-mΩ MOSFETs, i-IQ ephantsi kunye nokutsiba kwe-pulse kwimithwalo elula.Ukusebenzisa i-pin yokuvumela, umbane wokucima ukuvala uyancipha ukuya kwi-2 μA.Esi siguquli se-step-down (i-buck) sinikeza ummiselo ochanekileyo kwiintlobo ezahlukeneyo zemithwalo kunye nereferensi yombane elawulwa kakuhle eyi-1.5% ngaphezu kweqondo lokushisa.
Umda womjikelo-ngomjikelo wangoku kwicala eliphezulu le-MOSFET ukhusela usapho lwe-TPS5433xA lwezixhobo kwiimeko ezigcwala kakhulu kwaye yongezwa ngumda wangoku wokukhangela osezantsi othintela ukubaleka kwangoku.Umda wokuzikisa kwicala elisezantsi ucima iMOSFET ekwicala elisezantsi ukunqanda umva ngokugqithisileyo.Ukukhuselwa kwe-Hiccup kubangelwa ukuba imeko ye-overcurrent iqhubeka ixesha elide kunexesha elimiselweyo.Ukuvalwa kwe-Thermal kukhubaza isixhobo xa ubushushu bokufa budlula umqobo kwaye buye kwenza isixhobo kwakhona emva kwexesha le-thermal hiccup eyakhelwe-ngaphakathi.
1. Ngoobani abasebenzi kwisebe lakho le-R & D?Ziziphi iziqinisekiso zakho?
-R & D UMlawuli: yenza isicwangciso sexesha elide seR & D senkampani kwaye ubambe isikhokelo sophando kunye nophuhliso;Ukukhokela kunye nokulawula isebe le-r&d ukuphumeza isicwangciso se-r&d yenkampani kunye nesicwangciso sonyaka se-R&D;Lawula inkqubela phambili yophuhliso lwemveliso kwaye uhlengahlengise isicwangciso;Misela uphando lwemveliso egqwesileyo kunye neqela lophuhliso, uphicotho kunye noqeqesho olunxulumene nabasebenzi bobugcisa.
