LP87702DRHBRQ1 Waxyaalaha Elektrooniga ah ee Isku-dhafan ee Tayada Sare ee Cusub & Asalka ah

LP87702DRHBRQ1 Tayo Sare Cusub & Asalka Isku-dhafka Wareega ee Elektaroonigga ah ee ku jira Sawirka Kaydka ah

sharaxaad gaaban:

LP87702-Q1 wuxuu caawiyaa buuxinta shuruudaha maaraynta awooda ee aaladaha ugu dambeeyay, gaar ahaan raadaarka baabuurta iyo kamaradaha iyo codsiyada raadaarka warshadaha.Qalabku waxa uu ka kooban yahay laba beddelayaasha DC/DC, iyo 5-V-gacan beddelka si ay u taageeraan codsiyada muhiimka ah ee badbaadada.Qalabku wuxuu isku daraa laba qalab oo la socodka korantada oo loogu talagalay sahayda korantada dibadda iyo ilaaliye daaqada.
Hawlgalka tooska ah ee PWM/PFM (qaabka AUTO) wuxuu bixiyaa waxtar sare leh oo ka badan baaxadda wax soo saarka ballaaran ee hadda jira ee beddelayaasha buckka.LP87702-Q1 waxay isticmaashaa dareemada danab fog si ay u magdhabiso hoos u dhaca IR ee u dhexeeya wax soo saarka beddelka iyo barta-load, sidaas darteed hagaajinta saxnaanta tamarta wax soo saarka.

PMIC?

I. Waa maxay PMIC
PMIC waa soo gaabinta maaraynta awooda IC, muuqaalka ugu muhiimsan waa shahaadada is dhexgalka sare, xirmada tamarta wax soo saarka badan ee soo jireenka ah ee chip si marka codsiga awoodaha badan uu u yeesho hufnaan sare, iyo cabbir yar.PMIC-yada waxaa badanaa lagu isticmaalaa nidaamyada CPU, sida naqshadaynta sanduuqa-sare, naqshadaynta codka hadalka ee caqliga leh, naqshadaynta qalabka xakamaynta warshadaha, iwm.
Hal PMIC waxay maareyn kartaa sahay koronto oo badan oo dibadda ah, iyada oo u samaynaysa shuruudaha nidaamka kala duwan ee tamarta wax soo saarka ee habboon.Waxa kale oo loo isticmaali karaa noocyo kala duwan oo soo-saareyaal ah, kontaroolayaasha nidaamka, iyo codsiyada dhamaadka, waxay u baahan yihiin oo keliya isbeddelada goobaha diiwaangelinta ee khuseeya ama firmware, iyada oo aan loo baahnayn in dib loo habeeyo wareeg cusub oo isku dhafan (IC).

Suuqa PMIC wuxuu ku korayaa boodbood iyo xuduud sababtoo ah dhowr isbeddel oo hadda jira.Mid ka mid ah isbeddellada ayaa ah raadinta macaamilka ee dhaqdhaqaaqa wireless-ka, kaas oo abuuray baahi weyn oo loogu talagalay aaladaha yar yar, ee ku shaqeeya baytariyada iyo baahida keentay baahida loo qabo xalal maamul oo awoodeed oo heersare ah oo isku dhafan.
Isla mar ahaantaana, waxaa jira dalabaad isa soo taraya oo ka imaanaya macaamiisha iyo kuwa wax soo saara ee alaabooyinka tamarta fiican leh oo yareeya qiiqa kaarboonka.Isbeddelka caalamiga ah ee "cagaaran" wuxuu kordhiyey baahida alaabooyinka elektiroonigga ah oo leh maamul awood hufan leh, taas oo ka dhigaysa maamulka awoodda sifo aad u muhiim ah oo caan ah.

Hawlaha ugu muhiimsan

Hawlaha ugu muhiimsan ee PMIC: [Maareynta korantada, kantaroolka dallaca, beddelka wareegga xakamaynta]

- beddelka DC-DC
- Xakamaynta korantada ee hooseeya (LDO)
- Dameeraha baytari
- Doorashada sahayda korontada
- Nidaaminta danab firfircoon
- Kontoroolka isku xigxiga ee dami ama dami sahay koronto kasta
- Ogaanshaha Voltage ee sahay koronto kasta
- Heerkulka oo la ogaado
- Shaqooyin kale

Inta badan ee sahayda korontadu leedahay PMIC, way sii fiicnaanaysaa sahayda korantada ee qaybaha nidaamka, way yaraanaysaa sahayda korantada ee module kasta, sidaas darteed bad baadinta tamarta.
