Infineon technologies introduced XDP ™ digital power XDPL8221 platform of LED application series of new members

New trends in smart lighting and the Internet of things call for a new generation of LED drivers.Infineon technologies introduced XDP ™ digital power LED application of the new members of the series XDPL8221 platform, help to realize intelligent lighting.The device is "PFC+Flyback" integrated control IC, PSR control, and with communication interface.The all-new IC drive was demonstrated at the APEC2019 in Anaheim, California.

XDPL8221 has many advanced functions, can achieve constant voltage, constant current and constant power control, operating parameters can be configured through the GUI.This helps engineers easily design multi-function and high-performance LED drivers.

The XDPL8221 scheme can achieve high efficiency.The driver IC supports a wide input voltage range of 100 VAC ~ 277 VAC or 127 VDC ~ 430 VDC.The digital control system built into IC will switch between quasi-resonant, discontinuous conduction (DCM) or Active Burst Mode according to the input and load conditions to achieve the optimal operation Mode.

XDPL8221 with communication interface, is the ideal choice of intelligent lighting system LED Driver.The Driver IC can provide the running state information of the LED Driver through the UART interface, and the control system can control it.

The drive IC can achieve as low as 1% stroboscopic dimming, while the current regulation can still ensure high precision.The chip also provides dim-to-off dimming for low standby power when the lights are off (less than 100 mW, depending on the drive design).

XDPL8221 can reduce BOM material and minimize total system cost.XDPL8221 adopts the dso-16 package, which is easy to design with the support of debugging tools. In this way, the product design cycle can be shortened and the step of bringing the product to market can be accelerated.
