Muaj kev txawj ntse hauv kev faib tawm thiab kev siv hluav taws xob tswj IC chips

Lub hwj chim tswj nti IC yog lub chaw muab hluav taws xob thiab kev sib txuas ntawm tag nrho cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob, lub luag haujlwm rau kev hloov pauv, kev faib tawm, kev tshawb nrhiav thiab lwm yam kev tswj hwm ntawm lub zog xav tau, yog ib qho tseem ceeb ntawm cov khoom siv hluav taws xob thiab khoom siv.Nyob rau tib lub sijhawm, nrog rau kev txhim kho hauv Is Taws Nem ntawm Tej Yam, lub zog tshiab, kev txawj ntse, neeg hlau thiab lwm yam kev thov tawm tshiab, kev lag luam hauv qab ntawm lub hwj chim tswj chips tau txais kev txhim kho tshiab.Cov hauv qab no yog los qhia txog kev faib tawm, daim ntawv thov thiab kev txiav txim siab ntawm kev tswj fais fab IC chip ntsig txog kev txawj ntse.

Lub zog tswj chip kev faib tawm

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 (tso tawm 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.

 

Ob, daim ntawv thov ntawm lub hwj chim tswj nti

Lub peev xwm ntawm kev tswj fais fab yog qhov dav, suav nrog tsis yog tsuas yog kev hloov pauv hluav taws xob ywj pheej (tsuas yog DC rau DC, xws li DC / DC), kev faib hluav taws xob ywj pheej thiab kev tshawb pom, tab sis kuj tseem muaj kev sib koom ua ke hloov hluav taws xob thiab kev tswj hwm hluav taws xob.Raws li, kev faib tawm ntawm lub hwj chim tswj nti kuj suav nrog cov yam ntxwv no, xws li cov kab hluav taws xob nti, hluav taws xob siv hluav taws xob, hloov hluav taws xob nti, LCD tsav tsheb nti, LED tsav tsheb nti, ntsuas hluav taws xob nti, roj teeb tswj cov nti thiab lwm yam.

Yog hais tias tus tsim ntawm lub Circuit Court rau lub hwj chim mov nrog lub suab nrov thiab ripple supple, thov kom coj mus rau hauv me me PCB cheeb tsam (xws li, mobile xov tooj thiab lwm yam khoom siv hluav taws xob handheld), lub hwj chim mov Circuit Court tsis pub siv inductor (xws li xov tooj ntawm tes). , ib ntus calibration thiab tso zis lub xeev lub hwj chim yuav tsum tau kuaj tus kheej muaj nuj nqi, siab poob yuav tsum tau voltage stabilizer thiab nws tsis muaj hwj chim noj, txoj kab uas tsis muaj nqi thiab yooj yim tov, ces linear fais fab mov yog qhov kev xaiv tsim nyog tshaj.Cov khoom siv hluav taws xob no suav nrog cov thev naus laus zis hauv qab no: kev siv hluav taws xob precision, kev ua haujlwm siab, tsis tshua muaj suab nrov ua haujlwm amplifier, tsis tshua muaj hluav taws xob poob regulator, tsis tshua muaj hluav taws xob zoo li qub.

Ntxiv rau qhov yooj yim zog hloov dua siab tshiab nti, lub hwj chim tswj nti kuj suav nrog lub hwj chim tswj nti rau lub hom phiaj ntawm kev siv lub hwj chim.Xws li NiH roj teeb ntse them nyiaj ceev ceev, lithium ion roj teeb them thiab kev tswj xyuas nti, lithium ion roj teeb dhau voltage, dhau tam sim no, dhau kub, luv Circuit Court tiv thaiv nti;Nyob rau hauv kab fais fab mov thiab thaub qab roj teeb hloov tswj nti, USB hwj chim tswj nti;Charge twj tso kua mis, multi-channel LDO fais fab mov, lub zog sib txuas tswj, ntau yam kev tiv thaiv, roj teeb nqi thiab kev tswj xyuas kev siv zog nti, thiab lwm yam.

Tshwj xeeb tshaj yog nyob rau hauv cov khoom siv hluav taws xob.Piv txwv li, portable DVD, xov tooj ntawm tes, lub koob yees duab digital thiab lwm yam, yuav luag nrog 1-2 daim ntawm lub hwj chim tswj nti tuaj yeem muab ntau txoj kev siv hluav taws xob, kom qhov kev ua tau zoo ntawm qhov system mus rau qhov zoo tshaj plaws.

 

Peb, motherboard hwj chim tswj nti zoo los yog phem kev txawj txiav txim

Motherboard hwj chim tswj nti yog ib qho tseem ceeb heev motherboard, peb paub hais tias ib tug tivthaiv ua hauj lwm kom tau raws li tus mob no, ib tug yog voltage, lwm yam yog lub hwj chim.Motherboard hwj chim tswj nti yog lub luag hauj lwm rau qhov voltage ntawm txhua feem ntawm lub motherboard nti.Thaum lub motherboard tsis zoo muab tso rau pem hauv ntej ntawm peb, peb tuaj yeem kuaj xyuas lub zog tswj nti ntawm lub motherboard thiab saib seb lub nti puas muaj qhov tso zis hluav taws xob.

1) Ua ntej tshaj plaws tom qab lub mainboard fais fab tswj nti tawg lawm, CPU yuav tsis ua hauj lwm, uas yog hais tias, yuav tsis muaj kub tom qab lub mainboard yog powered ntawm CPU, lub sij hawm no koj yuav siv tau lub diode kais ntawm lub 'meter'. los ntsuas qhov tsis kam ntawm inductor coil thiab hauv av yog tias lub 'meter' poob ib qho kev tiv thaiv tus nqi nce los ua pov thawj tias lub zog tswj nti yog qhov zoo, ntawm qhov tsis sib xws, muaj teeb meem.

2) Yog tias cov khoom siv hluav taws xob peripheral zoo li qub tab sis qhov hluav taws xob ntawm lub hwj chim tswj nti tsis zoo li qub, koj tuaj yeem tshawb xyuas qhov voltage ntawm FIELD effect raj G ncej, xws li them nyiaj rau cov nqi sib txawv, thiab paub tseeb tias qhov hwj chim tswj chip yog faulty.
