Ukutshintsha uMlawuli

I-switching regulator sisilawuli sombane esisebenzisa into etshintshayo ukuguqula unikezelo lwamandla angenayo kwi-pulsed voltage, ethi emva koko igudiswe kusetyenziswa i-capacitors, inductors, kunye nezinye izinto.
Amandla anikezelwa ukusuka kwigalelo ukuya kwimveliso ngokuvula i-Switch (MOSFET) de kufike umbane ofunekayo.
Nje ukuba i-voltage yemveliso ifikelele kwixabiso elimiselweyo into yokutshintsha ivaliwe kwaye akukho mandla okufaka asetyenziswayo.
Ukuphinda lo msebenzi ngesantya esiphezulu kwenza kube lula ukubonelela amandla ombane ngokufanelekileyo kunye nokuveliswa kobushushu obuncinci.

Inkcazelo ye-TPS54560B-Q1

I-TPS54560B-Q1 yi-60 V, i-5 A, i-step down regulator kunye ne-MOSFET ephezulu edibeneyo.Isixhobo sisinda kwi-pulses yokulahla imithwalo ukuya kwi-65V nge-ISO 7637. Ulawulo lwemowudi yangoku lubonelela ngembuyekezo elula yangaphandle kunye nokukhethwa kwecandelo eliguquguqukayo.Imowudi yokutsiba ukubetha kwentliziyo esezantsi yehlisa unikezelo lwangoku lokungabikho komthwalo ukuya kwi-146 µA.Ukucinywa konikezelo lwangoku kucuthwe ukuya kwi-2 µA xa iphini lokuvula litsalwa phantsi.
I-Undervoltage lockout isetelwe ngaphakathi kwi-4.3 V kodwa inokunyuswa ngokusebenzisa i-pin yokuvula.I-voltage ephumayo yokuqalisa irempu ilawulwa ngaphakathi ukuze ibonelele ngokuqalisa okulawulwayo kunye nokuphelisa ukugqithiswa.
Uluhlu olubanzi lokutshintshela rhoqo luvumela ukuba ukusebenza kakuhle okanye ubungakanani becandelo langaphandle buphuculwe.Imveliso yangoku ilinganiselwe kumjikelo-ngomjikelo.Ukuphindaphinda rhoqo kunye nokuvalwa kwe-thermal kukhusela amacandelo angaphakathi nangaphandle ngexesha lomthwalo ogqithisiweyo.
I-TPS54560B-Q1 iyafumaneka kwiphakheji ye-HSOP PowerPAD™ yesi-8.
