TPS54331DR Imipira yumuzingi IC chip

TPS54331DR Yuzuzanya Yumuzingi IC chip Ikiranga

ibisobanuro bigufi:

Igikoresho cya TPS54331 ni 28-V, 3-A idahuza buck ihindura ihuza RDS yo hasi (kuri) MOSFET yo hejuru.Kugirango wongere imikorere yumutwaro woroheje, impanuka isimbuka Eco-moderi irahita ikora.Byongeye kandi, 1-μA guhagarika gutanga-bigezweho bituma igikoresho gikoreshwa muri porogaramu zikoreshwa na bateri.Kugenzura uburyo bugezweho hamwe nindishyi zimbere byoroshya kubara indishyi zo hanze kandi bigabanya kubara ibice mugihe wemera gukoresha ubushobozi bwa ceramic.Porogaramu igabanya gahunda ya hystereze yinjiza munsi ya volvoltage.Umuvuduko ukabije wumuzenguruko urinda imipaka igabanya ingufu za voltage mugihe cyo gutangira nigihe gito.Umuzenguruko-by-cycle igezweho-ntarengwa gahunda, inshuro nyinshi kugaruka no guhagarika ubushyuhe birinda igikoresho numutwaro mugihe habaye ibintu birenze urugero.
Igikoresho cya TPS54331 kiraboneka muri 8-pin ya SOIC hamwe na 8-pin SO PowerPAD yamashanyarazi imbere kugirango itezimbere imikorere yubushyuhe.

Guhindura ibiyobora nuburyo bwiza cyane bwo guhindura voltage ya DC iyindi voltage ya DC.Kandi muri topologiya zose zidasanzwe DC / DC - buck, kuzamura, kuzamura-kuzamura no guhinduranya - turagufasha kongera imikorere yimikorere ya voltage igenzura IC hamwe ninganda nini zatoranijwe mu guhindura DC / DC, modules hamwe nubugenzuzi.

Ubucucike bw'imbaraga

Imbaraga nyinshi, umwanya muto wibibaho.Byerekanwe na SWIFT ™ buck igenzura umuryango, portfolio yacu yibikoresho byimbaraga nyinshi zishyizwe hamwe cyane, hamwe nibikorwa byinshi biranga ibintu hamwe nibisohoka-bigezweho mubushobozi buke, bipfunyika cyane.
Abashinzwe kugenzura ibintu byinshi cyane ni amahitamo meza yo gukoresha ingufu zigezweho za digitale nka FPGAs hamwe nabatunganya.Koresha ibikoresho byacu-mugerekaho ibikoresho kugirango ubone ibicuruzwa byiza byuzuza FPGA cyangwa itunganya.

EMI yo hasi

Kugabanya uburyo bwo guhindura ibintu EMI birashobora kuba ikibazo gikomeye kubantu benshi bashushanya amashanyarazi.Ibikoresho byubatswe muri tekinoroji ya EMI igabanya igihe cyo gushushanya mugihe igufasha kubahiriza ibipimo bigoye nka CISPR 25 Class-5.Reba ibicuruzwa byacu byerekanwe hepfo kuri bimwe bigezweho kandi byiza bya DC / DC byahinduye imikorere ya EMI.

Umuyoboro muto (IQ)

DC / DC ihinduranya hamwe na ultra-low quiescent iriho byongera urumuri-umutwaro kandi byongerera igihe cya bateri mubikoresho byoroshye kandi bikoreshwa na batiri.Shakisha bimwe mubikoresho byo hasi bya IQ murwego rwohinduranya portfolio hepfo.

Urusaku ruto & precision

Ubusanzwe guhinduranya ibintu bisaba post-igenzura LDO kugirango ikemure cyane-ADCs na AFEs.Ariko hamwe nurusaku rwiza rwinganda hamwe nibikorwa bya Ripple, TPS62912 na TPS62913 bigufasha kuvanaho urusaku ruke LDO mubisabwa byinshi, uzigama agace ka PCB nigiciro rusange mugihe uzamura imikorere ya sisitemu.
