Kev tswj fais fab IC chips feem ntau tswj hluav taws xob hloov hluav taws xob, kev faib tawm, kev tshawb nrhiav thiab lwm yam kev tswj fais fab hauv cov khoom siv hluav taws xob.Kev tswj fais fab semiconductor los ntawm cov khoom siv, qhov tseem ceeb ntawm kev tswj fais fab kev sib xyaw ua ke (kev tswj fais fab IC, hu ua fais fab tswj nti) txoj hauj lwm thiab lub luag haujlwm.Kev tswj hwm hluav taws xob semiconductor suav nrog ob ntu, uas yog kev tswj hwm hluav taws xob sib xyaw ua ke thiab kev tswj hwm hluav taws xob discrete semiconductor ntaus ntawv.
Muaj ntau ntau hom kev tswj fais fab kev sib xyaw ua ke, uas tuaj yeem muab faib ua cov kev tswj hluav taws xob thiab kev sib txuas sib txuas.Voltage modulator muaj xws li linear low voltage drop regulator (ie LOD), zoo thiab negative output series circuit, ntxiv rau, tsis muaj mem tes dav modulation (PWM) hom switching circuit, thiab lwm yam.
Vim yog kev vam meej hauv kev lag luam, lub cev loj ntawm cov digital Circuit Court nyob rau hauv kev sib xyaw ua ke chips tau dhau los ua qhov me thiab me, yog li cov khoom siv hluav taws xob ua haujlwm tau txhim kho mus rau qhov tsis tshua muaj hluav taws xob, thiab cov hluav taws xob hluav taws xob tshiab tau tshwm sim rau lub sijhawm.Kev tswj fais fab interface feem ntau suav nrog tus tsav tsheb interface, tsav tsheb, tsav tsheb MOSFET thiab high voltage / high tam sim no zaub tsav tsheb, thiab lwm yam.
Feem ntau yim hom kev tswj fais fab IC nti kev faib tawm
Kev tswj fais fab sib cais cov khoom siv semiconductor suav nrog qee cov khoom siv hluav taws xob ib txwm siv, uas tuaj yeem muab faib ua ob pawg, ib qho suav nrog rectifier thiab thyristor;Lwm qhov yog hom triode, suav nrog lub zog bipolar transistor, muaj MOS qauv fais fab teb cov nyhuv transistor (MOSFET) thiab insulated gate bipolar transistor (IGBT).
Ib feem vim yog kev loj hlob ntawm kev tswj hwm hluav taws xob, hluav taws xob semiconductors tau hloov npe hu ua hluav taws xob tswj hluav taws xob semiconductors.Nws yog qhov tseeb vim tias muaj ntau yam sib xyaw ua ke (IC) rau hauv cov khoom siv hluav taws xob, tib neeg muaj ntau dua rau kev tswj hwm hluav taws xob los hu rau theem tam sim no ntawm lub tshuab hluav taws xob.
Kev tswj fais fab semiconductor nyob rau hauv cov thawj coj ntawm lub hwj chim tswj IC, tuaj yeem kwv yees kwv yees li hauv qab no 8.
1. AC/DC modulation IC.Nws muaj tsawg voltage tswj Circuit Court thiab high voltage switching transistor.
2. DC / DC modulation IC.Xws li boost/step-down regulators, thiab them twj tso kua mis.
3. fais fab kev tswj PFC pretuned IC.Muab lub hwj chim input Circuit Court nrog lub hwj huam hloov kho muaj nuj nqi.
4. pulse modulation los yog mem tes amplitude modulation PWM/PFM tswj IC.Pulse zaus modulation thiab / lossis mem tes dav modulation maub los rau kev tsav tsheb sab nraud.
5. linear modulation IC (xws li linear low voltage regulator LDO, thiab lwm yam).Xws li rau pem hauv ntej thiab tsis zoo regulators, thiab tsawg voltage poob LDO modulation raj.
6. roj teeb them thiab tswj IC.Cov no suav nrog cov roj teeb them, kev tiv thaiv thiab lub zog tso saib ics, nrog rau "ntse" roj teeb ics rau kev sib txuas lus cov ntaub ntawv roj teeb.
7. Kub swap board tswj IC (tsim los ntawm kev cuam tshuam los yog tshem tawm lwm qhov cuam tshuam los ntawm kev ua haujlwm).
8. MOSFET lossis IGBT hloov ua haujlwm IC.
Ntawm cov kev tswj fais fab no, kev tswj hluav taws xob hluav taws xob ICS yog qhov loj tshaj plaws thiab ua tau zoo tshaj plaws.Ntau yam kev tswj hwm lub zog ics feem ntau cuam tshuam nrog ntau cov ntawv thov cuam tshuam, yog li ntau hom khoom siv tuaj yeem teev npe rau cov ntawv thov sib txawv.
Cov txheej txheem ntawm kev tswj fais fab yog kev ua haujlwm siab, kev siv hluav taws xob tsawg thiab kev txawj ntse.Kev txhim kho kev ua tau zoo muaj ob yam sib txawv: ntawm ib sab, kev ua haujlwm tag nrho ntawm kev hloov hluav taws xob yog khaws cia thaum txo qhov loj ntawm cov khoom siv;Ntawm qhov tod tes, kev tiv thaiv qhov loj me tsis hloov pauv, txhim kho kev ua haujlwm zoo heev.
Tsis tshua muaj kev tiv thaiv hauv xeev hauv AC / DC kev hloov pauv raws li qhov xav tau rau cov khoom siv hluav taws xob ntau dua thiab cov khoom siv hluav taws xob hauv kev siv computer thiab kev sib txuas lus.Hauv kev tsim hluav taws xob tsim hluav taws xob, kev siv hluav taws xob dav dav tau raug txo kom qis dua 1W, thiab lub zog hluav taws xob tuaj yeem nce mus rau ntau dua 90%.Txhawm rau txo qhov kev siv hluav taws xob tam sim no, IC tsim thev naus laus zis tshiab thiab kev ua tiav hauv kev tsim hluav taws xob qis hluav taws xob yog xav tau.
