Itsva Yekutanga Yakabatanidzwa Circuit TPS63070RNMR

tsananguro pfupi:

Iyo TPS6307x inoshanda zvakanyanya, yakaderera ikozvino buck-boost converter inokodzera maapplication uko magetsi ekuisa anogona kunge akakwira kana kudzika pane inobuda voltage.Mapoinzi ekubuda anogona kuenda akakwira se2 A muboost mode uye mune buck mode.Iyo buck-boost inoshandura yakavakirwa pane yakatemwa frequency, pulse-width modulation (PWM) controller uchishandisa synchronous rectification kuti uwane yakanyanya kunaka.Pamhepo yakaderera mitoro, inoshandura inopinda Power Save Mode kuti ichengetedze kushanda kwepamusoro pamusoro peyakakura mutoro wazvino renji.Iyo inoshandura inogona kuvharwa kuti ideredze kupera kwebhatiri.Panguva yekuvhara, mutoro unobviswa kubva mubhatiri.Chishandiso ichi chinowanikwa mune 2.5 mm x 3 mm QFN package.

Nhanganyaya

A switching regulator (DC-DC converter) is regulator (yakagadzikana magetsi).A switching regulator inogona kushandura inopinza yakananga ikozvino (DC) voltage kune inodiwa yakananga ikozvino (DC) voltage.
Mune yemagetsi kana imwe mudziyo, switching regulator inotora basa rekushandura voltage kubva kubhatiri kana imwe sosi yemagetsi kuenda kumagetsi anodiwa neanotevera masisitimu.

Sezvinoratidzwa nemufananidzo uri pazasi, switching regulator inogona kugadzira inobuda voltage (V_OUT) iyo yakakwira (nhanho-kumusoro, kusimudzira), yakaderera (nhanho-pasi, buck) kana ine polarity yakasiyana neiyo yemagetsi ekuisa (V_IN)
Kushandura regulator maitiro

Izvi zvinotevera zvinopa tsananguro yezvisiri zvega switching regulator maitiro.

Kubudirira kwepamusoro

Nekushandura chinhu chinoshandura ON uye OFF, chigadziriso chekugadzirisa chinogonesa kushandiswa kwemagetsi kwepamusoro-soro sezvo inopa huwandu hunodiwa hwemagetsi chete kana zvichidiwa.
A linear regulator ndiyo imwe mhando ye regulator (yakagadzikana magetsi ekupa), asi nekuti inobvisa chero yakasara sekupisa mukati meiyo voltage yekushandura process pakati peVIN neVOUT, haina kuita senge yakanyatsoita senge switching regulator.

Noise

Iyo switching element ON/OFF mashandiro mune switching regulator inokonzeresa shanduko yemagetsi uye yazvino, uye maparasitic zvikamu zvinoburitsa kurira, izvo zvese zvinounza ruzha mumhepo inobuda.
Kushandisa chimiro chebhodhi chakakodzera kunoshanda mukuderedza ruzha.Semuenzaniso, kugadzirisa kuiswa kwecapacitor uye inductor uye / kana wiring.Kuti uwane rumwe ruzivo nezve magadzirirwo eruzha (kurira) uye kuti inodzorwa sei, tarisa kune Chiziviso Chekushandisa "Step-Down switching Regulator Noise Countermeasures."
