Yeqa-ukushintsha umjikelezo wokulawula okukhiphayo ekulayisheni okulula
14-Phina iphakheji ye-HTSSOP ene-PowerPad™
Dala idizayini yangokwezifiso usebenzisa i-TPS61175 ngeWEBENCH Power Designer
Incazelo ye-TPS61175
Idivayisi ye-TPS61175 iyisilawuli sokushintshwa kwe-monolithic esine-3-A ehlanganisiwe, i-40-V powerswitch.Idivayisi ingalungiswa ngezihloko ezimbalwa ezijwayelekile zesilawuli sokushintsha, okuhlanganisa i-boost, i-SEPIC, ne-flyback.Lolu cingo lunobubanzi bevoltheji yokufaka ebanzi ukuze lusekele ukusetshenziswa kwamandla kagesi aphuma kumabhethri amaningi noma alawulwayo angu-5-V, 12-V omzila wamandla.
I-TPS61175 ilawula amandla kagesi okukhiphayo ngokushintshashintsha kobubanzi be-pulse mode yamanje (PWM).Imvamisa yokushintsha ye-PWM isethwe yi-resistor yangaphandle noma isignali yewashi yangaphandle.Umsebenzisi angakwazi ukuhlela imvamisa yokushintsha isuka ku-200 kHz iye ku-2.2 MHz.
Lolu cingo lunomsebenzi ohlelekayo wokuqalisa okuthambile ukuze ukhawulele ukungena kokungena ngesikhathi sokuqalisa, futhi inezinye izici zokuvikela ezakhelwe ngaphakathi, ezifana nomkhawulo we-overcurrent we-pulse-by-pulse kanye nokuvalwa kokushisa.I-TPS61175 iyatholakala ngephakeji ye-HTSSOP yamaphini angu-14 nge-PowerPad.
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
