♠ TPS92638-Q1 8-Channel Linear LED Tsav Nrog PWM Dimming
TPS92638-Q1 yog yim-channel linear LED tsav tsheb nrog PWM dimming tswj. Nws tsim yog qhov zoo tagnrho rau kev tsav tsheb ntau txoj hlua ntawm LEDs mus txog qhov nruab nrab
lub zog ntau.
Cov cuab yeej no tuaj yeem tsav mus txog yim txoj hlua nrog ib mus rau peb LEDs hauv txhua txoj hlua, ntawm tag nrho cov tam sim no mus txog 70 mA ib channel. Cov zis tawm tuaj yeem ua rau tib lub sijhawm los muab cov tsav tam sim no siab dua mus txog 560 mA.
Hauv kev siv ntau txoj hlua, cov cuab yeej muaj qhov zoo ntawm kev sib txuas-cathode ntawm LED stings. Yog li, tsuas yog ib qho xaim xaim xaim rov qab tsuas yog xav tau ib qho ntawm ib txoj hlua LED uas lub kaw lus uas tsis tshua muaj siab tam sim no xav tau.
Cov cuab yeej muaj peev xwm hloov LED tam sim no ntawm qhov siab tam sim no thiab qis tam sim no rau kev siv nres thiab tus Tsov tus tw. Ob qhov siv resistors teeb tsa ob theem LED tam sim no los ntawm txhua qhov tso zis.
Qhov ntsuas kub ntsuas nrog txo cov LED tsav tam sim no yog tias IC hlws ris kub tshaj qhov ntsuas kub. Qhov kub thiab txias yog programmable los ntawm ib tug sab nraud resistor. Ib tus tuaj yeem cuam tshuam lub thermal tam sim no-saib feature los ntawm kev txuas TEMP tus pin rau hauv av. Cov zis ntawm qhov sib txuas qhov kub thiab txias raws li qhov sib txawv voltage yog muaj raws li lub Hoobkas kev xaiv.
