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 asCoolMOSTM, 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 primary side and ZCS (zero current switching) on the secondary side are achieved through the means of regulating both positive and negative magnetizing current to increase efficiency. In addition, transformer leakage energy is recycled, thereby further increases efficiency. The XDPS2201 comes highly integrated with a 600 V start-up cell and an integrated high-side driver for ease of design and BOM cost reduction. A comprehensive suite of protection features including brown-in and -out, dual-level overcurrent, output over-voltage, output under-voltage and overtemperature via an external NTC to increase system robustness.
