UmLawuli womgca
Njengoko igama layo libonisa, umlawuli womgca ngomnye apho icandelo lomgca (njengomthwalo ochasayo) lisetyenziselwa ukulawula imveliso.
Kwakhona ngamanye amaxesha kuthiwa yi-series regulator kuba izinto zolawulo zicwangciswe ngokulandelelana phakathi kwegalelo kunye nemveliso.
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-TPS7B7701-Q1
Usapho lwe-TPS7B770x-Q1 lwezixhobo lubonisa umlawuli omnye kunye nembini, i-high-voltage low-dropout regulator (LDO) enengqiqo yangoku, eyenzelwe ukusebenza ngoluhlu olubanzi lwe-voltage ukusuka kwi-4.5 V ukuya kwi-40 V (45-V ukhuseleko lokulahla umthwalo. ).Ezi zixhobo zibonelela ngamandla kwi-amplifiers ephantsi yomsindo we-antenna esebenzayo ngekhebula le-coax kunye ne-300 mA ngesiteshi sangoku.Isitishi ngasinye sikwabonelela ngombane wokuphuma ohlengahlengiswayo ukusuka kwi-1.5 V ukuya kwi-20 V.
Ezi zixhobo zibonelela ngoxilongo ngengqiqo yangoku kunye nezikhonkwane zempazamo.Ukubeka iliso kumthwalo wangoku, i-high-side current-sensor circuitry ibonelela ngemveliso ye-analog elinganayo kumthwalo obonakalayo wangoku.Uluvo lwangoku oluchanekileyo luvumela ukuchongwa kweemeko ezivulekileyo, eziqhelekileyo, kunye nezifutshane ngaphandle kwesidingo sokuhlengahlengiswa.Ingqiqo yangoku inokuphinda iphindwe phakathi kwamajelo kunye nezixhobo zokugcina izixhobo ze-analog-to-digital converter (ADC).Itshaneli nganye iphinda isebenzise umda wangoku ohlengahlengiswayo kunye ne-resistor yangaphandle.
I-diode edibeneyo ye-reverse polarity isusa isidingo se-diode yangaphandle.Ezi zixhobo zibonisa ukuvalwa kwe-thermal, ukhuseleko olufutshane ukuya kwibhetri kwimveliso, kunye nokukhusela umva ngoku.Ijelo ngalinye linokhuseleko lwe-inductive clamp yangaphakathi kwimveliso ngexesha lokucinywa kwe-inductive.
Ezi zixhobo zisebenza ngaphezu kwe -40 °C ukuya +125 °C kuluhlu lobushushu bendawo.
