TPS54331DR Integrated Circuit IC chip

incazelo emfushane:

Idivayisi ye-TPS54331 iyi-28-V, 3-A isiguquli sebhaka esingavumelanisi esihlanganisa i-RDS(on) esezingeni eliphezulu ye-MOSFET.Ukuze kwandiswe ukusebenza kahle ekulayishweni okulula, isici se-pulse jumping Eco-mode sivulwa ngokuzenzakalela.Ngaphezu kwalokho, i-1-μA yokuvala shaqa-yamanje ivumela idivayisi ukuthi isetshenziswe ezinhlelweni ezisebenza ngebhethri.Ukulawula imodi yamanje ngesinxephezelo seslope sangaphakathi kwenza izibalo zesinxephezelo sangaphandle zibe lula futhi kunciphisa isibalo sezingxenye kuyilapho kuvumela ukusetshenziswa kwama-capacitor okukhipha ubumba.I-resistor divider ihlela i-hysteresis yokuvala i-output undervoltage.Isekhethi yokuvikela okwedlula i-overvoltage yesikhashana ikhawulela ukudutshulwa kwamandla kagesi ngesikhathi sokuqalisa kanye nezimo zesikhashana.Isikimu somkhawulo wamanje womjikelezo womjikelezo, ukugoqa imvamisa nokuvala shaqa okushisayo kuvikela idivayisi kanye nomthwalo esimweni sesimo sokugcwala kakhulu.
Idivayisi ye-TPS54331 iyatholakala kuphakheji ye-SOIC engu-8-pin kanye nephakheji ye-SO PowerPAD engu-8 ethuthukiswe ngaphakathi ukuze kuthuthukiswe ukusebenza okushisayo.

Ukushintsha izilawuli kuyindlela ephumelela kakhulu yokuguqula i-voltage eyodwa ye-DC iye kwenye i-DC voltage.Futhi kuwo wonke ama-topology e-DC/DC angahlukanisiwe - mbandi, i-boost, i-buck-boost kanye ne-inverting - sikusiza ukuthi ukhulise ukusebenza kwesilawuli sakho samandla kagesi i-IC ngokukhethwa okukhulu kwemboni kweziguquli ze-DC/DC, amamojula amandla nezilawuli.

Ukuminyana kwamandla

Amandla engeziwe, isikhala esincane sebhodi.Iqokonyiswa umndeni we-SWIFT™ buck regulator, iphothifoliyo yethu yamadivayisi asebenza ngamandla amakhulu ahlanganiswe kakhulu, anamasethi ezici ezisebenza kahle kakhulu namandla amanje okukhiphayo ekupakishweni okuhlangene, okuthuthukiswe ukushisa.
Izilawuli zokushintsha ezinomthamo omkhulu ziyinketho enhle ukunika amandla imithwalo yamanje yedijithali efana nama-FPGA namaphrosesa.Sebenzisa ithuluzi lethu lokunamathisela i-processor ukuze uthole imikhiqizo engcono kakhulu ehambisana ne-FPGA yakho noma iphrosesa.

I-EMI ephansi

Ukunciphisa isilawuli sokushintsha i-EMI kungaba inselele enkulu kubaklami abaningi abahlinzeka ngamandla.Amadivayisi anobuchwepheshe obakhelwe ngaphakathi bokunciphisa i-EMI bonga isikhathi sokuklama ngenkathi ekusiza ukuthi uthobelane namazinga anzima njenge-CISPR 25 Class-5.Bheka imikhiqizo yethu efakiwe ngezansi ukuze uthole ezinye zezishintshi zakamuva nezingcono kakhulu ze-DC/DC zokusebenza kwe-EMI.

I-Quescent current ephansi (IQ)

Izilawuli zokushintsha ze-DC/DC ezine-ultra-low quiescent zamanje zikhulisa ukusebenza kahle kokulayisha ukukhanya futhi zandise impilo yebhethri ezinhlelweni eziphathwayo nezisebenza ngebhethri.Thola amanye amadivayisi aphansi e-IQ kuphothifoliyo yethu yokushintsha ngezansi.

Umsindo ophansi nokunemba

Izilawuli ezijwayelekile zokushintsha zidinga i-post-regulator LDO ukuze inike amandla ama-ADC nama-AFE anokucaca okuphezulu.Kodwa ngomsindo ongcono kakhulu womkhakha nokusebenza kwe-ripple, i-TPS62912 ne-TPS62913 ikuvumela ukuthi ususe leyo LDO enomsindo ophansi ezinhlelweni eziningi, ulondoloze indawo ye-PCB kanye nezindleko eziphelele ngenkathi uthuthukisa ukusebenza kahle kwesistimu.
