ISekethe eNtsha yoqobo eDityanisiweyo ye-TPS63070RNMR

inkcazelo emfutshane:

I-TPS6307x yindlela esebenza ngayo kakhulu, i-converter ephantsi ye-buck-boost yangoku ephantsi ilungele usetyenziso apho i-voltage yegalelo ingaba phezulu okanye ngaphantsi kune-voltage ephumayo.Imisinga yemveliso inokuya phezulu njenge-2 A kwimowudi yokunyusa kunye nakwimowudi yebhaki.I-buck-boost converter isekelwe kwi-frequency esisigxina, isilawuli se-pulse-width modulation (PWM) usebenzisa ukulungiswa kwe-synchronous ukufumana ukusebenza kakuhle.Kwimisinga yomthwalo ophantsi, isiguquli singena kwiNdlela yokuGcina Amandla ukugcina ukusebenza kakuhle kuluhlu olubanzi lwangoku.Isiguquli sinokucinywa ukunciphisa umjelo webhetri.Ngexesha lokuvala, umthwalo uyanqanyulwa kwibhetri.Isixhobo sifumaneka kwiphakheji ye-2.5 mm x 3 mm QFN.

Intshayelelo

I-switching regulator (i-DC-DC converter) ngumlawuli (unikezelo lwamandla oluzinzile).Umlawuli wokutshintsha unokuguqula i-voltage ye-input yangoku (DC) kwi-voltage efunekayo yangoku (DC).
Kwisixhobo sombane okanye esinye isixhobo, umlawuli wokutshintsha uthatha indima yokuguqula amandla ombane ukusuka kwibhetri okanye komnye umthombo wamandla ukuya kumandla ombane afunwa ziinkqubo ezilandelayo.

Njengoko umzekeliso ongezantsi ubonisa, isilawuli esitshintshayo sinokwenza i-voltage ephumayo (V_PHUMA) ephezulu (inyathelo-phezulu, i-bout), esezantsi (inyathelo-ezantsi, i-buck) okanye ine-polarity eyahlukileyo kunaleyo yombane wegalelo (V_IN)
Ukutshintsha iimpawu zomlawuli

Oku kulandelayo kunika inkcazo yeempawu zokulawula ukutshintshwa kwe-non-yedwa.

Ukusebenza okuphezulu

Ngokuvula i-element switching ON and OFF, i-switching regulator yenza ukuguqulwa kombane ophezulu kakhulu njengoko inika umlinganiselo ofunekayo wombane kuphela xa kuyimfuneko.
Umlawuli womgca lolunye uhlobo lomlawuli (unikezelo lwamandla oluzinzile), kodwa ngenxa yokuba luchitha nayiphi na i-surplus njengobushushu kwinkqubo yokuguqula umbane phakathi kwe-VIN kunye ne-VOUT, ayiphantse yasebenza kakuhle njengomlawuli wokutshintsha.

Ingxolo

Into yokutshintsha i-ON / OFF imisebenzi kwi-switching regulator ibangela utshintsho ngokukhawuleza kwi-voltage kunye ne-current, kunye ne-parasitic components ezivelisa ukukhala, zonke ezizisa ingxolo kwi-voltage ephumayo.
Ukusebenzisa uyilo olufanelekileyo lwebhodi kuyasebenza ekudambiseni ingxolo.Umzekelo, ukwenza ngcono ukubekwa kwe-capacitor kunye ne-inductor kunye / okanye i-wiring.Ngolwazi oluthe kratya malunga nendlela ingxolo eyenziwa ngayo (ukukhalisa) kunye nendlela elawulwa ngayo, bhekisa kwiNqaku leSicelo “Inyathelo lokuTshintsha iSilawuli seNgxolo esiNyathelo-Phantsi.”
