Thandizani mawu a BOM Chatsopano Choyambirira Chophatikiza Circuit TPS7B6950QDBVRQ1

Kufotokozera mwachidule:

Chipangizo cha TPS7B69xx-Q1 ndi chowongolera chotsika chotsika chopangidwira mpaka 40-VV._Intchito.Pokhala ndi 15-µA (yodziwika) yokhayokha yomwe imagwira ntchito pang'onopang'ono, chipangizochi ndi choyenera kumayendedwe a microcontrol unit makamaka pamagalimoto.

Zipangizozi zimakhala ndi chitetezo chophatikizika chachifupi komanso chowonjezera.Chipangizo cha TPS7B69xx-Q1 chimagwira ntchito pa -40 ° C mpaka 125 ° C kutentha.Chifukwa cha zinthuzi, zida za TPS7B6925-Q1, TPS7B6933-Q1, ndi TPS7B6950-Q1 ndizokwanira pamagetsi pamagalimoto osiyanasiyana.

M'dziko la zipangizo zamagetsi, magetsi oyendetsa magetsi ndi amodzi omwe amagwiritsidwa ntchito kwambiri, koma IC iyi imachita chiyani?Amapereka dera lodziwikiratu komanso lokhazikika nthawi zonse, mosasamala kanthu za voteji yolowera.

Momwe ma voltage regulator amakwaniritsira ntchitoyi pamapeto pake zili ndi wopanga.Magetsi ena amatha kuwongoleredwa ndi diode yosavuta ya Zener, pomwe ntchito zina zimafunikira ma topology apamwamba kapena owongolera osinthira.Kumapeto kwa tsiku, wowongolera magetsi aliyense amakhala ndi cholinga choyambirira ndi chachiwiri:

Choyambirira:Kupanga voteji yokhazikika ya dera potengera kusiyanasiyana kwamagetsi olowera.Mutha kukhala ndi 9V mkati, koma ngati mukufuna kuti 5V ituluke, muyenera kuyitsitsa (Buck) ndi chowongolera magetsi.

Sekondale: Owongolera ma Voltage amagwiranso ntchito kutchingira ndi kuteteza madera anu amagetsi kuti asawonongeke.Chomaliza chomwe mukufuna ndikuwotcha microcontroller yanu chifukwa sinathe kuthana ndi kukwera kwamagetsi.

Zikafika pakuwonjezera chowongolera chamagetsi kudera lanu, nthawi zambiri mumagwira ntchito ndi imodzi mwamitundu iwiri - Ma Linear Voltage Regulators kapena Switching Voltage Regulators.Tiyeni tiwone momwe zonsezi zimagwirira ntchito.
