Ukutshintsha abalawuli
Ukutshintsha abalawuli luhlobo lwesekethe olunokuguqula i-voltage kunye ne-input current ibe yi-voltage kunye ne-output current eyona ifaneleke kakhulu ukunika amandla inkqubo evelisa amandla kuyo.Ezi ntlobo zeesekethe zikwabizwa ngokuba ngabaguquli kwaye zilungele ukulawula amandla ahanjiswa phakathi kwala manqaku mabini oqhagamshelwano ukuze kugcinwe i-voltage ephuma rhoqo ekhuselekileyo ngaphakathi kwemida yesekethe.Basebenza kwi-conversion esebenzayo ephezulu kakhulu kunokoabalawuli bemigcakunye nokubonelela ngenzuzo yolawulo lwamandla olungcono kunye neendleko eziphezulu kwixesha elide, kunye nenyaniso yokuba kaninzi ayifuni i-capacitors yangaphandle.
Zisetyenziselwa ntoni izilawuli zokutshintsha?
Ezi ntlobo zabalawuli zihlala zisetyenziselwa i-cell-cell okanye i-multi-cell-powered battery-powered applications kunye nebhetri-powered portable electronic devices like digital cameras, handheld games consoles, controlles and more.Inzuzo ephambili yokusebenzisa ezi ziguquli zokutshintsha endaweni yabalawuli bomgca kukuba banikezela ukhuseleko lwesiphaluka esifutshane kunye nokuqinisekisa ukukhuselwa kwe-voltage kunye ne-under-voltage.Zikwalungile ekukhuseleni iinkqubo zombane kubushushu obugqithisileyo kunye nomonakalo wangoku.
Iindidi zokutshintsha abalawuli
I-Step-Up okanye i-Boost Regulators-Ezona ntlobo zisisiseko zesilawuli sokutshintsha kwaye zisetyenziselwa ukonyusa amandla ombane.
Iziguquli zeNyathelo-Ezantsi okanye ze-Buck-Boost-Banciphisa okanye bawubuyise umva umbane ophumayo ngokubhekiselele kumbane wokufakelwa.

Inkcazelo ye-LP87524J-Q1
I-LP87524B/J/P-Q1 yenzelwe ukukhawulelana neemfuno zolawulo lwamandla eeprosesa zamva nje kunye namaqonga kwizicelo ezahlukeneyo zamandla emoto.Isixhobo siqulathe ii-cores ezine ze-DC-DC converter, eziqwalaselwe njengeziphumo ezi-4 zesigaba esisodwa.Isixhobo silawulwa ngu-I2Ujongano lwe-serial oluhambelana ne-C kunye nokwenza imiqondiso.
Ukusebenza okuzenzekelayo kwePFM/PWM (imowudi ye-AUTO) yandisa ukusebenza kakuhle kuluhlu olubanzi lwemveliso-yangoku.I-LP87524B/J/P-Q1 isekela i-remote voltage sensing ukubuyisela i-IR drop phakathi kwe-regulator output kunye ne-point-of-load (POL) ngaloo ndlela iphucula ukuchaneka kombane wokuphuma.Ukongeza iwotshi yokutshintsha inokunyanzeliswa kwimodi ye-PWM kwaye ilungelelaniswe newotshi yangaphandle ukunciphisa ukuphazamiseka.
Isixhobo se-LP87524B/J/P-Q1 sixhasa umlinganiselo womthwalo wangoku ngaphandle kokongezwa kwe-resistors yangaphandle yangoku.Ukongeza, i-LP87524B/J/P-Q1 ixhasa ukuqala okucwangcisiweyo kunye nokulibaziseka kokuvalwa kunye nolandelelwano olulungelelanisiweyo ukwenza imiqondiso.Ulandelelwano lunokubandakanya iimpawu ze-GPIO ukulawula abalawuli bangaphandle, ukutshintshwa komthwalo kunye nokusetha kwakhona iprosesa.Ngexesha lokuqalisa kunye nokutshintsha i-voltage, isixhobo silawula isantya sokubulala ukunciphisa i-voltage overshoot kunye ne-in-rush yangoku.
