Perancangan Led Driver 8watt Dengan Output Konstan Topologi Buck
Abstract
LED driver merupakan rangkaian yang telah banyak dikembangkan didalam dunia perindustrian. Karena LED driver memiliki fitur seperti berikut, direct control of current, high efficiency, PWM dimming, over voltage protection, load disconnect, small size, dan kemudahan penggunaan. Adapun fitur tersebut memerlukan sistem operasi switching cepat yang dapat menimbulkan EMI. Pada proyek akhir ini, dibuat rangkaian LED driver 8 watt dengan output konstan topologi buck dengan switching tunggal sebagai kendali dari led driver. Dengan menggunakan topologi buck, nilai efesiensi yang dihasilkan sangat besar yaitu 90%. LED driver yang diukur bekerja sesuai standar CISPR 22 setelah tegangan Vadj diatas nilai 0.5 V. Dengan tegangan Vadj 1.2 dihasilkan tegangan output dan arus output sebesar 0.99A dan 11.56 V sehingga daya yang dihasilkan sebesar 11.44 watt. Dengan EMI yang di timbulkan sebesar 55.52 dBuV.References
