Ibisobanuro kuri TPS92513HV
TPS92513 / HV ni 1.5A kumanura hasi (buck) kugenzura hamwe na MOSFET ihuriweho kugirango itware LED ndende.Kuboneka hamwe na 42 V na 60 V (HV) ibyinjira byinjira, aba bashoferi ba LED bakorera kumukoresha watoranijwe uhoraho-hamwe nuburyo bwo kugenzura no gutanga umurongo mwiza no kugenzura imizigo.
Abashoferi ba TPS92513 / HV LED bagaragaza inyongeramusaruro zinyuranye zo kugereranya na pulse ubugari bwa modulisiyo (PWM) gucogora kugirango hatabaho kugenzura ububengerane bugera ku kigereranyo kirenze 10: 1 kandi kirenga 100: 1.Iyinjizwa rya PWM rirahujwe na voltage ntoya ya logique ya interineti yoroshye kumurongo mugari wa microcontrollers.Ikigereranyo cya LED igezweho irashobora guhindurwa kuva 0 V kugeza 300 mV ukoresheje icyinjijwe cya IADJ hamwe nikimenyetso cya 0 V kugeza 1.8 V.
Kubikorwa byinshi-ukoresheje porogaramu ebyiri cyangwa nyinshi za TPS92513 / HV LED, oscillator y'imbere irashobora gutwarwa nisaha yo hanze yemeza ko abahindura bose bakora kumurongo umwe bityo bikagabanya ubushobozi bwo gukubita no koroshya sisitemu ya EMI.Guhindura ibyinjira munsi ya voltage gufunga (UVLO) hamwe na hystereze itanga guhinduka mugutangiza / guhagarika voltage ukurikije imiterere ya voltage.
TPS92513 ikubiyemo cycle-by-cycle birenze urugero kurinda no guhagarika ubushyuhe.Iraboneka muri 10-pin ya HVSSOP PowerPAD ™ paki.
1. Ni bande bakozi mu ishami rya R & D?Ni ubuhe bushobozi bwawe?
-R & D Umuyobozi: gutegura gahunda yigihe kirekire yikigo no gusobanukirwa icyerekezo cyubushakashatsi niterambere;Kuyobora no kugenzura ishami rishyira mubikorwa ingamba za sosiyete na gahunda ya R&D yumwaka;Kugenzura iterambere ryibicuruzwa no guhindura gahunda;Shiraho ibicuruzwa byiza byubushakashatsi niterambere, kugenzura no guhugura abakozi ba tekiniki bijyanye.
Umuyobozi wa R & D: kora ibicuruzwa bishya R & D hanyuma werekane ko bishoboka gahunda;Kugenzura no gucunga iterambere nubuziranenge bwakazi;Kora ubushakashatsi ku bicuruzwa bishya kandi utange ibisubizo bifatika ukurikije ibyo umukiriya asabwa mubice bitandukanye
Abakozi & gukusanya: gukusanya no gutondekanya amakuru yingenzi;Porogaramu ya mudasobwa;Gukora ubushakashatsi, ibizamini nisesengura;Tegura ibikoresho nibikoresho byo kugerageza, kugerageza no gusesengura;Andika amakuru yo gupima, gukora ibarwa no gutegura imbonerahamwe;Kora ubushakashatsi bwibarurishamibare
2. Niki gitekerezo cyawe cyo gukora ubushakashatsi nibitekerezo byiterambere?
- Igitekerezo cyibicuruzwa no guhitamo ibicuruzwa nibisobanuro byerekana ibicuruzwa nibishushanyo mbonera byumushinga no kugerageza ibicuruzwa bitezimbere no kwemeza isoko
