Sharaxaada
Qoyska TPS9260x-Q1 ee aaladaha waa hal kanaal iyo laba-kanaal sare-dhinac-jooga LED
darawal.Iyada oo si buuxda loo ilaalinayo iyo ogaanshaha, qoyskan aaladaha ayaa u heellan oo ku habboon iftiinka hore ee baabuurta.Saldhigga darawal kasta oo madaxbannaan ayaa ah kontaroolaha kor u qaadaya qaabka ugu sarreeya- hadda.Koontaroole kastaa wuxuu leeyahay laba wareeg oo jawaab celin madax banaan, loop-celinta hadda oo leh shunt-dareenka hadda-sare ee dhinac-sare iyo wareegga jawaab-celinta danab-celinta oo leh shabakad wax-is-celin-celin-dibadeed ah.Xakameeyaha wuxuu keenaa koronto joogto ah ama wax soo saar joogto ah.Culayska ku xiran ayaa go'aamiya in qalabku uu nidaaminayo soo-saarka joogtada ah (haddii wareeggu gaaro goobta hadda la joogo ka hor inta aan la gaarin heerka korantada) ama koronto joogto ah (haddii wareeggu gaaro heerka korantada waxaa la gaaraa marka hore, tusaale ahaan, meel furan. Xakamaynta kasta waxay taageertaa dhammaan noocyada topologiyada caadiga ah sida asboost, boost-to-battery, SEPIC, ama flyback. Isticmaalka darawalka PMOS FET ee dhinaca sare ah ayaa loogu talagalay PWM khafiifinta xadhigga LED iyo goynta haddii ay dhacdo gaaban gaaban Wareegto GND si loo ilaaliyo wareegga.
