Infineon Presents XDPL8221 - the Device for Advanced, Smart and Connected LED Driver

The emerging trend of smart lighting and Internet of Things, requires a new generation of LED drivers. Infineon Technologies AG introduces the new member of its XDP™ LED series, the XDPL8221 for cost-effective dual-stage drivers with advanced features. This device combines a quasi-resonant PFC and a quasi-resonant flyback controller with primary side regulation together with a communication interface. A comprehensive set of configurable protection mechanisms (standard and sophisticated) ensure safe, reliable and robust LED driver for a large set of use cases. The new driver IC will be showcased at the APEC 2019 exhibition in Anaheim, CA.

•    The XDPL8221 enables the design of high performance and innovative
     advanced LED driver for connected lighting with small effort
•    Reduced BoM minimizes system cost and increases flexibility
•    High reliability features improve long lifetime of the driver
•    Fast design cycle reduces time to market and efforts for value products
•    Supply chain efficiency optimizes stock keeping and enables high flexibility
•    Real time operating parameters digitally available by UART interface
•    Dimming control numerically precise through UART commands

Target Applications:
•    Flicker-free LED driver for indoor or outdoor applications
•    Multi-mode LED driver for connected lighting
•    Wired or wireless connected LED driver

The XDPL8221 combines advanced functions, such as multi control featuring constant voltage, constant current and limited power as configurable operating parameters. The result is a versatile, high performance LED driver.

The performance of the XDPL8221 helps to design more efficient devices. This driver IC supports full functionality for both AC and DC input in the nominal input voltage range of 100 V AC to 277 V AC or 127 V DC to 430 V DC. Depending on the actual situation, the built-in digital control selects the best mode of operation. It can switch between quasi-resonant, discontinuous conduction or active burst modes.

The XDPL8221 UART interface with a command set enables control of the functions of the device and provides status information. This enables numerically exchanged real-time data. This data can be used for monitoring or additional local control functions.

This driver IC can be dimmed flicker free below one percent, while the current is still regulated with a high accuracy. The chip also offers a dim-to-off function to keep the device in a standby mode when the light is off with a low standby power (less than 100 mW, depending on driver design).

Reduced bill of materials (BOM) and increased flexibility minimize the overall system cost. The XDPL8221 comes in a DSO-16 package and, with a wide tool support, it is easy to design-in. This accelerates the design cycle and shortens time-to-market.

The new XDPL8221 is now available. More information is available at www.infineon.com/xdpl8221
