TPS54331DR Isku-dhafka Wareegga IC chip

TPS54331DR Isku-dhafan Wareegga IC-ga Sawirka

sharaxaad gaaban:

Qalabka TPS54331 waa 28-V, 3-A beddelaadaha buck-ka ah ee isku-xidha RDS(dhinaca) sare ee MOSFET.Si loo kordhiyo waxtarka culeysyada fudud, garaaca garaaca garaaca habka Eco-mode si toos ah ayaa loo hawlgelinayaa.Intaa waxaa dheer, 1-μA xidhitaanka sahayda- hadda waxay u oggolaanaysaa aaladda in loo isticmaalo codsiyada ku shaqeeya baytari.Xakamaynta qaabka hadda jirta ee leh magdhowga jiirada gudaha waxay fududaynaysaa xisaabinta magdhowga dibadeed waxayna yaraynaysaa tirada qaybaha iyada oo la ogolaanayo isticmaalka capacitors wax soo saarka dhoobada.Qaybiyaha iska caabbinta wuxuu barnaamijiyaa xifdiyada gelinta quful ka hooseeya.Wareegga ilaalinta ku-meel-gaadhka ah ee xad-dhaafka ah waxay xaddidaysaa korontada xad-dhaafka ah inta lagu jiro bilawga iyo xaaladaha ku-meel-gaadhka ah.Nidaamka xaddidan ee hadda-wareeg-wareegga ah, isku-laabashada soo noqnoqda iyo xiritaanka kulaylka ayaa ilaalinaya aaladda iyo culeyska haddii ay dhacdo xaalad culeys xad dhaaf ah.
Qalabka TPS54331 waxaa lagu heli karaa xirmo 8-pin SOIC ah iyo xirmo 8-pin SO PowerPAD ah oo gudaha lagu hagaajiyay si loo horumariyo waxqabadka kulaylka.

Beddelida nidaamiyayaasha ayaa ah habka ugu waxtarka badan ee loogu badalo hal danab oo DC ah oo loogu badalo danab kale oo DC ah.Iyo dhammaan dusha sare ee DC/DC-da aan go'doomin - buck, boost, buck-kobcinta iyo rogidda - waxaan kaa caawineynaa inaad sare u qaaddo waxqabadka maamulaha korantada IC xulashada ugu weyn ee warshadaha ee beddelayaasha DC/DC, kontaroolayaasha.

Cufnaanta awoodda

Awood badan, boos boodh yar.Waxaa iftiimiyay qoyska SWIFT ™ buck regulator, faylalkayaga aaladaha cufnaanta awoodda sare leh ayaa si heersare ah isku dhafan, oo leh qaabab qaabaysan oo tayo sare leh iyo karti-wax-soo-saar sare oo hadda ah oo ku jira baakado isku dhafan, heerkul sare leh.
Nidaamiyeyaasha beddelka cufnaanta sare ayaa ah doorasho weyn si loo xoojiyo rarka dhijitaalka ah ee hadda-sare sida FPGA-yada iyo soo-saareyaasha.Adeegso qalabkayaga-ku-xidhka processor-ka si aad u hesho alaabta ugu fiican si aad u buuxiso FPGA ama processor-kaaga.

EMI hoose

Yaraynta beddelka xeerbeegtida EMI waxay caqabad weyn u noqon kartaa naqshadeeyayaal badan oo awood-siinta ah.Aaladaha leh farsamada dhimista EMI-ku-dhisantahay waxay badbaadiyaan wakhtiga naqshadaynta iyagoo kaa caawinaya inaad u hogaansanto heerarka adag sida CISPR 25 Class-5.U fiirso alaabadayada hoos ku qoran qaar ka mid ah kuwa ugu dambeeyay iyo kuwa ugu wanaagsan ee DC/DC ee waxqabadka EMI.

Hadda degan yar (IQ)

Xakamaynta beddelka DC/DC ee leh hoos u-hooseeya hadda waxay kordhiyaan hufnaanta culayska iftiinka waxayna kordhiyaan nolosha batteriga codsiyada la qaadan karo iyo kuwa ku shaqeeya baytariga.Ka hel qaar ka mid ah aaladaha IQ-ga ugu hooseeya ee ku jira galka beddelka eeyaga hoose.

Sawaxanka hooseeya & saxnaanta

Nidaamiyeyaasha beddelka caadiga ah waxay u baahan yihiin maamulaha ka dambeeya LDO si loo xoojiyo ADC-yada iyo AFE-yada sare.Laakin iyadoo leh sanqadha ugu fiican ee warshadaha iyo waxqabadka rogrogmi kara, TPS62912 iyo TPS62913 waxay kuu oggolaanayaan inaad ka saarto LDO buuq yar inta badan codsiyada, badbaadinta aagga PCB iyo qiimaha guud iyadoo la hagaajinayo hufnaanta nidaamka.
