Chithunzi cha TPS65150RGER IC TRIPLE-OUT LCD 24-VQFN

Kufotokozera

Chipangizo cha TPS65150 chimapereka njira yophatikizika kwambiri komanso yaying'ono yamagetsi yomwe imapereka ma voltages onse atatu ofunikira ndi mawonedwe ochepera a film transistor (TFT) LCD.Ndi ma voliyumu olowetsamo a 1.8 V mpaka 6 V chipangizocho ndichabwino pamabuku oyendetsedwa ndi 2.5-V kapena 3.3-V njanji yolowera kapena kuyang'anira ntchito ndi njanji yamagetsi ya 5-V.Kuphatikiza apo, chipangizo cha TPS65150 chimapereka cholumikizira chapamwamba chamakono kuti chipereke voteji ya VCOM paulendo wakumbuyo wa TFT.Dalaivala iwiri yosinthika yosinthira pampu imapereka ma voliyumu abwino a V (VGH) ndi V (VGL) osakondera a TFT.Chipangizochi chimakhala ndi njira yosinthira mphamvu ya V(VGL) komanso V(VGH).Izi zimapewa zina zowonjezera zakunja kuti zigwiritse ntchito kutsatizana kwachindunji.Chipangizocho chili ndi cholumikizira champhamvu chamagetsi chophatikizira chopatula V(VGH).Dera lamkati lomwelo litha kugwiritsidwanso ntchito kupereka chizindikiro chopanga chipata cha V (VGH) cha gulu la LCD lomwe limayendetsedwa ndi siginecha yomwe imagwiritsidwa ntchito pakulowetsa kwa CTRL.Pachitetezo chapamwamba, chipangizo cha TPS65150 chili ndi cholumikizira cholumikizira chotsekera, chomwe chimalola kusinthasintha kwachindunji.Chipangizochi chimayang'anira zotuluka (V (VS), V (VGL), V (VGH));ndipo, mwamsanga pamene mmodzi wa zotuluka kugwera pansi mphamvu pakhomo zabwino, chipangizo amalowa shutdown latch, pambuyo chosinthika kuchedwa nthawi yadutsa.
