Infineon’s XDPL8210 Digital Constant-Current Flyback Controller Serves LED Systems

August 8, 2019 Alix Paultre

Infineon Technologies released the XDPL8210, an IC with a high-power factor and primary-side regulation. The 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, complemented by an output voltage that can be varied by a factor of three.

Features include a power factor of more than 0.9, and total harmonic distortion of less than 15 percent over the load and input range. The XDPL8210 fully supports the IEC61000-3-2 class C standard, a limited power mode improves functional safety, and the device has the ability for flicker-free dimming below 1 percent.

The XDPL8210 implements an adaptive temperature guard that prevents the driver hardware from thermal wear out. Additionally, adaptive overvoltage protection enables lower safety margins to meet safety extra low voltage (SELV) specifications. The XDPL8210 is available in DSO-8 package.
