As a member of the XDPL family of LED driver ICs with a digital core, the XDPL8210 supports a great variety of LED driver products, based on the same hardware design. Therefore, it improves the supply chain efficiency by reducing efforts and cost for stock keeping. Infineon’s new IC uses a PWM dimming input signal, and modulates the output current amplitude proportional to the duty cycle. A dim-to-off mode offers a standby power of less than 100 mW. The advanced feature set is complemented by an output voltage that can be varied by a factor of three.
Designed in a DSO-8 package, t he XDPL8210 boasts an excellent power factor of more than 0.9, and total harmonic distortion of less than 15 percent over a wide load and input range. It fully supports the IEC61000-3-2 class C standard, making it well-suited for contemporary LED luminaires. The limited power mode improves functional safety. Sophisticated algorithms provide flicker-free dimming below one percent. With this excellent light quality can even at low dimming levels be achieved. The XDPL8210 implements an adaptive temperature guard that prevents the driver hardware from thermal wear out. Additionally, the adaptive overvoltage protection enables lower safety margins to meet safety extra low voltage (SELV) specifications.
