♠ TPS92638-Q1 8-Channel Tooska LED Darawalka oo leh PWM Dimming
TPS92638-Q1 waa darawal toosan oo sideed kanaal ah oo LED ah oo leh kontoroolka dhimista PWM. Naqshadeedu waxay ku habboon tahay wadista xargaha badan ee LED-yada ilaa dhexdhexaad
baaxadda awoodda.
Qalabkani waxa uu wadi karaa ilaa siddeed xadhig oo leh hal ilaa saddex LEDs oo xadhig kasta ah, wadar ahaan hadda ilaa 70 mA kanaalka. Natiijooyinka waxay noqon karaan kuwo isbarbar socda si ay u bixiyaan wadista hadda sare ilaa 560mA.
Codsiyada xadhkaha badan, qalabku wuxuu bixiyaa faa'iidada lahaanshaha isku xirka-cathode-ka ee isugeynta LED-ka. Marka, waxaa jira kaliya hal silig soo celin ah oo loo baahan yahay halkii laga heli lahaa mid kasta oo xadhig LED ah oo nidaam leh dareenka hadda jira ee dhinaca hoose u baahan yahay.
Qalabku waxa uu awood u leeyahay in uu u beddelo hadda LED inta u dhaxaysa hadda sare iyo kan hoose ee joogsiga iyo codsiyada dabada. Laba caabiyeyaasha tixraaca ayaa dejinaya labada heer ee LED hadda wax soo saar kasta.
Kormeeraha heerkulka ku jira wuxuu yareeyaa hadda socodka LED-ka haddii heerkulka isgoyska IC uu dhaafo heerka kulaylka. Heerkulka heerkulku waxa lagu baran karaa iyada oo loo marayo iska caabin dibadeed. Mid ayaa joojin kara habka kulaylka hadda-kormeeraha isaga oo ku xidha biinka TEMP dhulka. Soo saarista heerkulka isgoysyada sida danab analooga ah ayaa diyaar u ah barnaamij warshadeed ahaan.
