I-TPS92513/HV izilawuli zamanje ze-step-down (i-buck) eziyi-1.5A ezine-MOSFET edidiyelwe ukushayela ama-LED aphezulu amanje.Itholakala ngobubanzi bokufaka okungu-42 V kanye no-60 V (HV), lawa madrayivu e-LED asebenza ngefrikhwensi ekhethiwe yomsebenzisi enokulawula kwemodi yamanje ephezulu futhi alethe ukulawulwa komugqa nokulayisha okuhle kakhulu.
Amashayeli e-TPS92513/HV LED afaka okokufaka okuhlukene kwe-analog ne-pulse wide modulation (PWM) ukufiphala ngaphandle kokulawula ukukhanya okuphazamisa okuzuza izilinganiso zokungafani ezinkulu kuno-10:1 nangaphezulu kuno-100:1, ngokulandelanayo.Okokufaka kwe-PWM kuhambisana namazinga anengqondo we-voltage ephansi ukuze kube lula ukuxhumana nohlu olubanzi lwama-microcontroller.Indawo yamanje ye-analog LED iyalungiseka ukusuka ku-0 V ukuya ku-300 mV kusetshenziswa okokufaka kwe-IADJ ngesignali yangaphandle engu-0 V ukuya ku-1.8 V.
Kuzinhlelo zokusebenza ezinezintambo eziningi ezisebenzisa izishayeli ze-LED ze-TPS92513/HV ezimbili noma ngaphezulu, i-oscillator yangaphakathi ingashayelwa ngokweqile iwashi langaphandle liqinisekisa ukuthi zonke iziguquli zisebenza ngefrikhwensi evamile ngaleyo ndlela kuncishiswe amandla okushaywa kwefrikhwensi nokwenza lula ukuhlunga kwe-EMI kwesistimu.Okokufaka okulungisekayo kwe-under-voltage lockout (UVLO) ene-hysteresis kunikeza ukuguquguquka ekusetheni ama-voltage okuqala/wokumisa ngokusekelwe kuzimo zamandla kagesi.
I-TPS92513 ifaka phakathi ukuvikeleka okudlulele komjikelezo nomjikelezo kanye nokuvikela ukuvala shaqa okushisayo.Itholakala ngephakeji ye-HVSSOP PowerPAD™ enamaphini angu-10.
1. Obani abasebenzi bomnyango wakho we-R & D?Yiziphi iziqu zakho?
-R & D Umqondisi: yenza uhlelo lwesikhathi eside lwe-R & D lwenkampani futhi babambe isiqondiso socwaningo nentuthuko;Qondisa futhi uqondise umnyango we-r&d ukuze usebenzise isu le-r&d lenkampani kanye nohlelo lonyaka lwe-R&D;Lawula inqubekelaphambili yokuthuthukiswa komkhiqizo futhi ulungise uhlelo;Misa ithimba locwaningo lomkhiqizo elihle kakhulu nelokuthuthukisa, abacwaningi mabhuku kanye nokuqeqeshwa okuhlobene nabasebenzi bezobuchwepheshe.
Umphathi we-R & D: yenza uhlelo olusha lwe-R & D futhi ubonise ukuthi kungenzeka uhlelo;Ukugada nokuphatha inqubekelaphambili kanye nekhwalithi yomsebenzi we-r&d;Cwaninga ukuthuthukiswa komkhiqizo omusha futhi uphakamise izixazululo ezisebenzayo ngokuvumelana nezidingo zamakhasimende emikhakheni ehlukene
Abasebenzi be-R&d: baqoqa futhi balungise idatha ebalulekile;Uhlelo lwekhompyutha;Ukwenza izivivinyo, izivivinyo kanye nokuhlaziya;Lungiselela izinto zokwakha kanye nezinto zokusebenza zokuhlola, izivivinyo nokuhlaziya;Rekhoda idatha yokulinganisa, yenza izibalo futhi ulungiselele amashadi;Yenza izinhlolovo zezibalo
2. Uthini umbono wakho wocwaningo nokuthuthukiswa komkhiqizo?
- Ukwakhiwa komkhiqizo kanye nomqondo wokukhethwa komkhiqizo kanye nokuhlolwa kwencazelo yomkhiqizo kanye nomklamo wepulani yephrojekthi kanye nokuthuthukiswa kokuhlolwa komkhiqizo kanye nokwethulwa kokuqinisekisa emakethe
