I-TPS65150RGER IC TRIPLE-OUT LCD SUPPLY 24-VQFN

Incazelo

Idivayisi ye-TPS65150 inikezela ngesixazululo esihlangene kakhulu nesincane samandla esihlinzeka ngawo wonke ama-voltages amathathu adingwa yi-film transistor (TFT) LCD displays.Ngobubanzi be-voltage yokufaka engu-1.8 V kuya ku-6 V idivayisi ilungele izincwadi zamanothi axhaswe yisitimela sokufaka esingu-2.5-V noma 3.3-V noma iqaphe izinhlelo zokusebenza ezinomzila we-voltage wokufaka ongu-5-V.Ukwengeza idivayisi ye-TPS65150 ihlinzeka ngebhafa yamanje ehlanganisiwe ephezulu ukuze inikeze amandla kagesi e-VCOM kundiza engemuva ye-TFT.Umshayeli wepompo oshintshwayo oshintshwayo obili uhlinzeka ngama-voltage athandwayo e-V(VGH) kanye ne-negative V(VGL) ye-TFT.Idivayisi ihlanganisa ukulandelana kwamandla okulungisekayo kwe-V(VGL) kanye ne-V(VGH).Lokhu kugwema noma yiziphi izingxenye zangaphandle ezengeziwe ukuze kusetshenziswe ukulandelana okuqondile kohlelo lokusebenza.Idivayisi inokushintsha okuhlanganisiwe kwe-high-voltage ukuhlukanisa i-V(VGH).Umjikelezo ofanayo wangaphakathi ungasetshenziswa futhi ukuze unikeze isignali yokubunjwa kwesango ye-V(VGH) yephaneli ye-LCD elawulwa isignali esetshenziswe kokokufaka kwe-CTRL.Ngokuphepha okuphezulu kakhulu, idivayisi ye-TPS65150 inesici se-latch esilungisekayo esilungisekayo esihlanganisiwe, esivumela ukuguquguquka okuqondile kohlelo lokusebenza.Idivayisi iqapha okuphumayo (V(VS), V(VGL), V(VGH));futhi, ngokushesha nje lapho okuphumayo okunye kuwela ngaphansi komkhawulo omuhle wamandla, idivayisi ingena endaweni yokuvala shaqa, ngemva kokuba isikhathi sayo sokulibaziseka esilungisekayo sesidlulile.
