Circuit Yatsopano Yophatikizidwa TPS63070RNMR

Chithunzi Chatsopano Chophatikizidwa ndi Circuit TPS63070RNMR

Kufotokozera mwachidule:

TPS6307x ndi njira yabwino kwambiri, yotsika pang'ono ya buck-boost converter yoyenera kugwiritsa ntchito pomwe magetsi olowera amatha kukhala okwera kapena otsika kuposa magetsi otulutsa.Mafunde otulutsa amatha kukwera mpaka 2 A mu boost mode komanso mu buck mode.Chosinthira cha buck-boost chimakhazikitsidwa ndi owongolera pafupipafupi, pulse-width modulation (PWM) pogwiritsa ntchito synchronous rectification kuti apeze bwino kwambiri.Pamafunde otsika kwambiri, chosinthiracho chimalowa mu Power Save Mode kuti chikhale chogwira ntchito kwambiri pamitundu yambiri yapano.Converter ikhoza kuyimitsidwa kuti muchepetse kukhetsa kwa batri.Panthawi yotseka, katunduyo amachotsedwa ku batri.Chipangizochi chikupezeka mu phukusi la 2.5 mm x 3 mm QFN.

Mawu Oyamba

switching regulator (DC-DC converter) ndi regulator (mphamvu yokhazikika).switching regulator imatha kusintha voliyumu yolowera molunjika (DC) kukhala voteji yomwe mukufuna (DC).
Mu chipangizo chamagetsi kapena china, switching regulator imatenga gawo losinthira voteji kuchokera ku batri kapena gwero lina lamagetsi kupita ku ma voltages ofunikira ndi makina otsatirawa.

Monga chithunzi chomwe chili pansipa chikuwonetsa, switching regulator imatha kupanga voliyumu yotulutsa (V_OUT) chomwe chili chapamwamba (chokwera, chokweza), chotsika (kutsika, thumba) kapena chili ndi polarity yosiyana ndi yamagetsi olowetsa (V_IN)
Kusintha mawonekedwe owongolera

Zotsatirazi zimapereka kufotokozera kwa mawonekedwe owongolera osinthika osadzipatula.

Kuchita bwino kwambiri

Poyatsa chinthu choyatsa ON ndi KUZIMA, chowongolera chosinthira chimathandizira kusinthika kwamagetsi apamwamba kwambiri popeza chimapereka kuchuluka kwamagetsi komwe kumafunikira pokhapokha pakufunika.
Linear regulator ndi mtundu wina wa regulator (magetsi okhazikika), koma chifukwa amataya zotsalira zilizonse monga kutentha munjira yosinthira voteji pakati pa VIN ndi VOUT, sizowoneka bwino ngati chowongolera chosinthira.

Phokoso

Kusintha kwazinthu ON / OFF mu chowongolera chosinthira kumayambitsa kusintha kwadzidzidzi kwa magetsi ndi apano, ndi zigawo za parasitic zomwe zimapanga kulira, zomwe zimabweretsa phokoso mumagetsi otulutsa.
Kugwiritsa ntchito makonzedwe oyenera a bolodi kumathandiza kuchepetsa phokoso.Mwachitsanzo, kukhathamiritsa kuyika kwa capacitor ndi inductor ndi/kapena mawaya.Kuti mumve zambiri pamakina a momwe phokoso (kulira) limapangidwira komanso momwe limayendetsedwa, onani Chidziwitso cha Ntchito "Step-Down Switching Regulator Noise Countermeasures."
