The emerging trend of smart lighting and Internet of Things, requires a new generation of LED drivers. InfineonTechnologies 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 flybackcontroller 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 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 VAC to 277 VAC or 127 VDC to 430 VDC. 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 FB can be configured to operate in Constant Voltage (CV), Constant Current (CC) or Limited Power (LP) mode offering a large degree of flexibility.
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).
