Infineon launches flyback controller for LED drivers

Infineon has launched the XDPL8210, a constant current flyback IC with a high power factor and primary-side regulation.

The XDPL8210 offers much improved functional performance for efficient designs as well as low bill-of-material (BOM) for small system cost and high flexibility. It also offers improved reliability for a long driver lifetime. For advanced products, the built-in features enable much faster design cycles..

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. It also 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 100mW. The advanced feature set is complemented by an output voltage that can be varied by a factor of three.

The devices has a power factor of more than 0.9, and total harmonic distortion of less than 15 percent over a wide load and input range. The XDPL8210 fully supports the IEC61000-3-2 class C standard making the device well-suited for contemporary LED luminaires. The limited power mode improves functional safety. Sophisticated algorithms provide flicker-free dimming below one percent

A set of comprehensive and configurable protection modes ensure product quality as well as safe and robust operation. 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.
