ADM00766

The ADM00766 from Microchip is a CL88020 LED driver evaluation board. The CL88020 LED driver integrated circuit (IC) is targeted at general LED lighting products such as A19 bulb with a maximum power rating of about 8.5W at 120VAC (60W incandescent equivalent bulbs). The CL88020 120VAC office LED driver evaluation board is a complete solution consisting of an LED driver (ADM00766) and an LED load board (ADM00767) powered directly from the 120VAC line and based on Microchip Technology's CL88020 sequential linear driver. The application achieves efficient operation without using any magnetics or conventional switching techniques and is a flexible solution that allows users to design and to test their own LED Load solution. The LED load is made with 10 LEDs. Since no high frequencies are present, it exhibits inherently low conducted and radiated EMI without needing input filters or shielding. The ADM00766 LED driver PCB is made on 1.6mm standard double layer FR4.
