The CL88020 120 VAC offline LED driver evaluation board is a complete solution consisting of an LED driver (ADM00766) and an LED load board (ADM00767) powered directly from the 120 VAC line and based on Microchip Technology's CL88020 sequential linear LED 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 included 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. Because the current through the LEDs follows the AC input voltage, PFC circuitry is also not needed. The CL88020 is inherently compatible with both leading-edge and trailing-edge dimmers, with no need for special circuitry to detect and respond to them.
The LED load is provided on a double-layer 60 mm diameter FR4 PCB (0.6 mm thick) mounted on a pin fin heat sink. The LED driver PCB (ADM00766) is made on 1.6 mm standard double-layer FR4. The kit includes an 8-wire flat cable to connect the LED driver board to the LED load, and a black anodized pin fin heat sink with double-sided adhesive thermal tape necessary to mount the LED load board on it. All circuitry and hardware is provided, along with transient protection and overtemperature protection.
* This is designed to be paired with the ADM00767-ND LED board with Heatsink.
