♠ TPS92638-Q1 8-Channel Linear LED Driver enePWM Dimming
I-TPS92638-Q1 ngumqhubi we-LED onomjelo osibhozo one-PWM yokulawula ubumnyama. Uyilo lwayo lufanelekile ukuqhuba iintambo ezininzi ze-LED ukuya kwindawo ephakathi
uluhlu lwamandla.
Esi sixhobo sinokuqhuba ukuya kuthi ga kwiintambo ezisibhozo kunye ne-LED enye ukuya kwezintathu kumtya ngamnye, ngokukhoyo ngoku ukuya kwi-70 mA ngetshaneli nganye. Iziphumo zinokuhambelana ukunika idrayivu ephezulu-yangoku ukuya kuthi ga kwi-560 mA.
Kwizicelo zeentambo ezininzi, isixhobo sibonelela ngenzuzo yokuba noqhagamshelo oluqhelekileyo lwe-cathode ye-LED stings. Ke, kukho intambo yokubuyisela enye kuphela efunekayo endaweni yomtya we-LED nganye enokuthi idingwe yinkqubo enecala eliphantsi langoku.
Isixhobo sinamandla okutshintsha i-LED yangoku phakathi kwangoku okuphezulu kunye nokuphantsi kwangoku kwizicelo zokumisa kunye nomsila. Izichasi ezimbini zereferensi ziseta amanqanaba amabini e-LED akhoyo ngoku kwimveliso nganye.
Iqondo lokushisa elibandakanyiweyo linciphisa i-LED drive yangoku ukuba ubushushu be-IC junction budlula umda we-thermal. Umda weqondo lobushushu ucwangciswa nge-resistor yangaphandle. Umntu unokukhubaza i-thermal current-monitor feature ngokudibanisa i-TEMP pin emhlabeni. Isiphumo sobushushu besiphambuka njengombane we-analog siyafumaneka njengokhetho lwenkqubo yefektri.
