Sekela ikhotheshini ye-BOM Entsha Yoqobo Ehlanganisiwe Yesekethe TPS7B6950QDBVRQ1

Sekela ikhotheshini ye-BOM Isekhethi Entsha Yoqobo Ehlanganisiwe TPS7B6950QDBVRQ1 Isithombe Esifakiwe

incazelo emfushane:

Idivayisi ye-TPS7B69xx-Q1 iyisilawuli somugqa esidonsela phansi esidizayinelwe kufika ku-40-VV_Iimisebenzi.Ngamanje ongu-15-µA (okuvamile) okuthule lapho kulayishwa khona ukukhanya, idivayisi ifanelekela amasistimu eyunithi ye-microcontrol-unit ikakhulukazi ezinhlelweni zokusebenza zezimoto.

Amadivayisi anokuvikela okuhlanganisiwe kwe-short-circuit kanye ne-overcurrent.Idivayisi ye-TPS7B69xx-Q1 isebenza ngaphezu kuka -40°C kuya ku-125°C izinga lokushisa.Ngenxa yalezi zici, amadivayisi we-TPS7B6925-Q1, TPS7B6933-Q1, kanye ne-TPS7B6950-Q1 afaneleka kahle ekunikezeni amandla kwezinhlelo zokusebenza zezimoto ezahlukahlukene.

Emhlabeni wezingxenye ze-elekthronikhi, isilawuli sikagesi singesinye esisetshenziswa kakhulu, kodwa le IC yenzani?Ihlinzeka ngesekhethi ene-voltage ephumayo ebikezelwayo nengaguquki ngaso sonke isikhathi, kungakhathaliseki ukuthi ingakanani i-voltage yokufaka.

Ukuthi isilawuli sikagesi siwufeza kanjani lo msebenzi ekugcineni kukumklami.Enye i-voltage ingalawulwa nge-Zener diode elula, kuyilapho ezinye izinhlelo zokusebenza zidinga i-topology ethuthukisiwe yezilawuli zomugqa noma ezishintshayo.Nokho, ekupheleni kosuku, zonke izilawuli zamandla kagesi zinenhloso eyinhloko neyesibili:

Okuyinhloko:Ukukhiqiza i-voltage ephumayo engaguquki yesekethe ngokuphendula ukuhluka kwezimo ze-voltage yokufaka.Ungase ube ne-9V ngaphakathi, kodwa uma ufuna kuphela ukuphuma kwe-5V, uzodinga ukuyehlisa (I-Buck) ngesilawuli sikagesi.

Okwesibili: Izilawuli zamandla kagesi nazo zisebenzela ukuvikela nokuvikela ukujikeleza kwakho kwe-elekthronikhi kunoma yimuphi umonakalo ongaba khona.Into yokugcina oyifunayo ukuthosa i-microcontroller yakho ngoba ayikwazanga ukuphatha i-spike ku-voltage.

Uma kuziwa ekwengezeni isilawuli sikagesi kusekethe yakho, uzosebenza ngokujwayelekile nenye yezinhlobo ezimbili - Izilawuli ze-Linear Voltage noma I-Switching Voltage Regulators.Ake sibone ukuthi zombili lezi zisebenza kanjani.
