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-TPS54360B
I-TPS54360B yi-60-V, 3.5-A, i-step-down regulator kunye ne-MOSFET ephezulu edibeneyo.Ulawulo lwemowudi yangoku lubonelela ngembuyekezo elula yangaphandle kunye nokukhethwa kwecandelo eliguquguqukayo.Imowudi yokutsiba i-ripple ephantsi yehlisa unikezelo lonikezelo olungalayishiyo lwangoku 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.Irempu yokuqalisa i-voltage ephumayo ilawulwa ngaphakathi ukuze ibonelele ngokuqalisa okulawulwayo kunye nokuphelisa ukudubula okugqithisileyo.
Uluhlu olubanzi lokutshintsha-frequency luvumela ukusebenza kakuhle okanye ubungakanani becandelo langaphandle ukuba luphuculwe.Ukuphindaphinda okuphindaphindiweyo kunye nokuvalwa kwe-thermal kukhusela amacandelo angaphakathi nangaphandle ngexesha lemeko yokulayisha ngaphezulu.
I-TPS54360B ifumaneka nge-8-pin eyomelezwe thermally iphakheji ye-HSOIC PowerPAD™.
