Bedelida Nidaamiyeyaasha
Habbeeyeyaasha beddelaadda waa nooc ka mid ah wareegyada u beddeli kara danabka iyo gelinta hadda oo u beddela danab iyo hadda jira oo ku habboon in lagu xoojiyo nidaamka uu awoodda u soo saarayo.Noocyada noocaan ah waxaa sidoo kale loo yaqaannaa beddelayaasha waxayna ku habboon yihiin habaynta tamarta lagu wareejiyo labadan qodob ee xiriirka si loo ilaaliyo koronto joogto ah oo wax soo saar leh oo si badbaado leh ugu dhex jira xadka wareegga.Waxay ku shaqeeyaan hufnaan beddelaad aad uga sarreeyanidaamiyayaal toosanwaxayna bixiyaan faa'iidada maaraynta awooda ka fiican oo ka badan oo kharash-ku-ool ah muddada fog, iyo sidoo kale xaqiiqda ah in aanay inta badan u baahnayn capacitors dibadda.
Maxaa loo istcmaalay xeer-beegtida?
Noocyada noocaan ah ayaa inta badan loo adeegsadaa codsiyada hal-unug ama unugyo badan oo ku shaqeeya baytari ku shaqeeya iyo aaladaha elegtarooniga ah ee la qaadan karo ee ku shaqeeya baytari sida kamaradaha dhijitaalka ah, consoles'ka ciyaaraha gacanta, kontaroolayaasha iyo wax ka badan.Faa'iidada ugu weyn ee isticmaalka beddelayaasha beddelka beddelka beddelka xeeriyeyaasha toosan waa inay bixiyaan ilaalin gaaban oo gaaban iyo inay xaqiijiyaan ilaalinta korantada xad-dhaafka ah iyo hoos-u-dhaca.Waxay sidoo kale ku fiican yihiin inay ka ilaaliyaan hababka elektaroonigga ah heerkulka xad-dhaafka ah iyo waxyeellada hadda jirta.
Noocyada xeer-beegtida
Kor-u-qaadista ama Kor-u-qaadista Nidaamiyeyaasha - Kuwani waa nooca ugu aasaasiga ah ee habeynta beddelka waxaana loo isticmaalaa in lagu kordhiyo korantada wax soo saarka
Beddeleyaasha Hoos-u-dhaca ama Kor-u-qaadista - Waxay yareeyaan ama rogaan korantada wax-soo-saarka marka loo eego tamarta wax-gelinta

Sharaxaada LP87524J-Q1
LP87524B/J/P-Q1 waxaa loogu talagalay in lagu buuxiyo shuruudaha maamulka awoodda ee soo-saareyaashii ugu dambeeyay iyo aaladaha codsiyada awoodda baabuurta ee kala duwan.Qalabku waxa uu ka kooban yahay afar qaybood oo hoos u socda DC-DC, kuwaas oo loo habeeyey sidii 4 weji oo soo saara.Qalabka waxaa gacanta ku haya I2C-ku-waabsan interface taxane ah iyo iyadoo la awood siinayo calaamadaha.
Hawlgalka tooska ah ee PFM/PWM (qaabka AUTO) waxa uu sare u qaadaa waxtarka baaxadda wax soo saarka- hadda.LP87524B/J/P-Q1 waxay taageertaa dareenka korantada fog si loo magdhabo hoos u dhaca IR ee u dhexeeya wax soo saarka nidaamiyaha iyo barta-load-load (POL) si loo hagaajiyo saxnaanta tamarta wax soo saarka.Intaa waxaa dheer saacadda beddelka waxaa lagu qasbi karaa qaabka PWM oo sidoo kale lala mid dhigo saacad dibadda ah si loo yareeyo qaska.
Qalabka LP87524B/J/P-Q1 wuxuu taageeraa cabbiraadda culeyska hadda socda iyada oo aan lagu darin iska caabiyeyaasha dareenka hadda jira.Intaa waxaa dheer, LP87524B/J/P-Q1 waxay taageertaa bilawga iyo daahitaanka barnaamijka iyo taxanaha la isku waafajiyay si loo suurtageliyo calaamadaha.Taxanuhu waxa kale oo ka mid noqon kara calaamadaha GPIO si loo xakameeyo nidaamiyayaasha dibadda, furayaasha rarka iyo dib u dajinta processor-ka.Inta lagu jiro bilawga iyo isbeddelka korantada, qalabku wuxuu maamulaa wax soo saarka wax soo saarka si loo yareeyo wax-soo-saarka xad-dhaafka ah iyo dhaqdhaqaaqa degdegga ah.
