Infineon Technologies XDP™ digital power XDPS2201

The XDP™ digital power XDPS2201 is a multi-mode, digitally configurable hybrid flyback controller that combines the simplicity of a traditional flyback topology with the performance of a resonant converter. By utilizing two high-voltage MOSFETs, such as CoolMOS™, the hybrid flyback XDPS2201 is able to drive both high- and low-side MOSFETs in an asymmetric half-bridge flyback topology. ZVS (zero voltage switching) on the primary side and Zero Current Switching (ZCS) on the secondary side are achieved through the means of regulating both positive and negative magnetizing current to increase efficiency.
