♠ TPS61196-Q1 6-xarigga 400-mA WLED Darawalka oo leh PWM madax-bannaan u dhimid Xarig kasta
TPS61196-Q1 waxay siisaa xal aad isku dhafan oo loogu talagalay iftiiminta gadaal LCD ee baabuurta oo leh shaqeyn madax-bannaan oo PWM ah oo xarig kasta ah.Qalabkani waa kontaroolaha kor u qaada qaabka hadda socda ilaa lix xadhig WLED oo leh LEDs badan oo taxane ah.Xadhig kastaa wuxuu leeyahay maamule madax banaan oo hadda jira oo bixiya LED hadda la hagaajin karo laga bilaabo 50 mA ilaa 400 mA gudaha ± 1.5% saxnaanta u dhigma.Korontada ugu yar ee saxanka hadda jira waa mid la bar-barangarayn karo inta u dhaxaysa 0.3 V ilaa 1 V si ay ugu habboonaato goobo kala duwan oo hadda LED ah.Qiyaasta korantada ee qalabka waa laga bilaabo 8 V ilaa 30 V.
TPS61196-Q1 waxay hagaajinaysaa korantada korantada korantada korantada si toos ah si ay u bixiso kaliya korantada looga baahan yahay xargaha LED-ka oo leh hoos u dhaca korantada ee ugu weyn oo lagu daray korantada ugu yar ee loo baahan yahay ee xarigga IFB pin, si kor loogu qaado hufnaanta darawalka.Inta jeer ee beddelkeeda waxa u habeeyey iska caabin dibadeed ka 100 kHz ilaa 800 kHz.
TPS61196-Q1 waxay taageertaa dhalaalka tooska ah ee PWM.Xadhig kastaa wuxuu leeyahay gelinta kontoroolka PWM madax banaan.Inta lagu jiro yaraynta PWM, hadda LED-ku waa la shidayaa ama dami doonaa inta jeer iyo wareegga shaqada kuwaas oo ay go'aamiso calaamada PWM ee dibadda ah.Inta jeer ee PWM waxay u dhaxaysaa 90 Hz ilaa 22 kHz.
TPS61196-Q1 waxay isku daraysaa ilaalinta xad dhaafka ah, soo saarida ilaalinta wareegga gaaban, ISET ilaalinta gaaban ilaa dhulka, difaac furan iyo gaaban, LED furan iyo ilaalin gaaban, iyo xiritaanka heerkulka xad-dhaafka ah.Intaa waxaa dheer, TPS61196-Q1 waxay ogaan kartaa IFB pin gaaban ilaa dhulka si loo ilaaliyo xadhigga LED.Qalabku waxa kale oo uu bixiyaa gelida barnaamijka la gelin karo ee qufulka korantada iyo heerka ilaalinta xad-dhaafka ah ee wax soo saarka.
