Product type Package Marking Firmware version Ordering code XDPL8218 PG-DSO-8 L8218 0.1.1.7 SP001707258 Description The XDPL8218 is a high performance configurable single-stage SSR flyback controller with high power factor, excellent standby power performance (< 100 mW typ.) and constant voltage output. The digital core of the XDPL8218 and its advanced control algorithms provide multiple operation modes such as QRM1, DCM or ABM. In addition, XDPL8218 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 efficienc y, high power factor and low harmonic distortion over wide load range. Operating parameters such as protection features are digitally configurable. Infineon offers a user friendly Graphic User Interface (GUI) for Personal Computer (PC)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 power supplies can be built with the same hardware using different XDPL8218 parameter sets. Note: By default, the configurable parameters of a new XDPL8218 chip from Infineon are empty, so it is necessary to configure them before any application testing. The system performance and efficienc y can be optimized using Infineon CoolMOS P7 power MOSFETs. Datasheet 2 Revision 1.0 2018-06-06
