♠ TPS5433xA 4.5-V ukuya 28-V Igalelo, 3-A Isiphumo, Synchronous Inyathelo-Phantsi DC-DC Converter
Intsapho ye-TPS5433xA yezixhobo ziguquli ze-synchronous kunye ne-input-voltage range ye-4.5 V ukuya kwi-28 V. Ezi zixhobo zibandakanya Esi sixhobo sine-FET edibeneyo yokutshintshwa kwecala elisezantsi eliphelisa imfuno ye-diode yangaphandle enciphisa ukubalwa kwamacandelo.
Ukusebenza kakuhle kunyuswa ngokudibeneyo i-128- mΩ kunye ne-84-mΩ MOSFETs, i-IQ ephantsi kunye ne-pulse skipping kwimithwalo elula. Ukusebenzisa i-pin yokuvumela, umbane wokucima ukuvala uyancipha ukuya kwi-2 μA. Lo mguquli we-step-down (i-buck) unikezela 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 i-MOSFET ekwicala elisezantsi ukunqanda umva ngokugqithisileyo wangoku. 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.
