3.0-mm x 3.5-mm 13-pin VQFN Hotrod Iphakheji
Dala Idizayini Ngokwezifiso Usebenzisa i-TPS61178 Nge-WEBENCH®Umklami Wamandla
Incazelo ye-TPS61178
Umndeni we-TPS61178x uyisiguquli se-20-V se-Boost esivumelanayo esinqamula ukulayisha komshayeli wesango owakhelwe ngaphakathi.I-TPS61178x ihlanganisa ama-FET amabili aphansi wamandla okumelana: I-16-mΩ switchingFET kanye ne-FET engu-16-mΩ yokulungisa kabusha.
I-TPS61178x isebenzisa isilawuli semodi yamanje ye-frequency ephezulu ene-slopecompensation ehlanganisiwe.Lapho ilayisha ukukhanya, i-TPS61178 ingena kumodi ye-PFM ezenzakalelayo kuyilapho i-TPS611781 ikumodi ye-PWM ephoqelelwe.
I-TPS61178x ingahlukanisa okukhiphayo ohlangothini lokokufaka lapho kuvaleka.Uma okukhiphayo sekufinyeziwe, kungena kumodi ye-hiccup ukuze kwehlise ukucindezelwa okushisayo futhi kungalulama ngokuzenzakalelayo ngemva kokukhishwa okufushane.Ukwengeza, i-TPS61178x futhi ine-OVP nokuvikelwa okushisayo ukugwema ukusebenza kwephutha.I-TPS61178x ikuphakheji ye-VQFN engu-3.0-mm x 3.5-mm 13-pin 13 enokuchithwa okuthuthukisiwe kokushisa.
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
