XDPL8210 Digital Flyback Controller IC XDP™ Digital Power Description Description
The XDPL8210 is a high performance configurable single-stage flyback controller with high power factor, primary side regulated constant current output and
LP
mode. The primary side control saves external components especially an opto coupler, thus reducing cost and effort and increasing reliability. With its integrated functionality, XDPL8210 enables an increase set of features without external parts. The digital core of the XDPL8210 and its advanced control algorithms provide multiple operation modes such as
QRM1
,
DCM
or
Active Burst Mode (ABM)
. In addition, XDPL8210 includes an enhanced
PFC
function which can partially compensate the effect of the input capacitance on power factor and harmonic distortion. With this functionality and smooth transition between the operation modes, the controller delivers high efficiency, high power factor and low harmonic distortion over wide load range. The active burst mode control scheme significantly extends the dimming range and is synchronized with the line frequency avoiding effects like flicker while reducing audible noise. Operation parameters such as the output current, dimming curve and the protection features are digitally configurable. Infineon offers a user friendly
Graphic User Interface
for
Personal Computer
s, allowing rapid engineering changes without the need for complex component design iterations. Functionality can be defined at the end of the production line. Multiple different
Light Emitting Diode (LED)
drivers can be built with the same hardware using different XDPL8210 parameter sets. For instance, the dimming curve shape is configurable to linear or quadratic (eye-adaptive) and can optionally be inverted. Additionally, dim-to-off can be enabled or disabled. Note: By default, the configurable parameters of a new XDPL8210 chip from Infineon are empty, so it is necessary to configure them before any application testing. The system performance and efficiency can be optimized using Infineon CoolMOS P7 power MOSFETs.
