Dr. Flyback™ for Optimal Efficiency (95% to 96%) & Power Density Resonant Flyback
●Almost Always ZVS for both switches to reduce EMI filters size and to reduce transformer size fsw VEAO-clamped=2.0V: Laser Trim for Switching Frequency Selection in Light Load Mode Ready for GaN or SiC
●GENERAL DESCRIPTION
■Dr. Flyback™ is the industry first Resonant Flyback controller with integrated Super Junction Mosfet (SJMOS):
▲TSSOP package:
◆Dr. Flyback™ system’s both switches (High Side Mosfet and Low Side Mosfet) are Almost Always Zero Voltage Switching (ZVS). As the results, its efficiency is ~2% higher than the traditional Quasi-Resonant (QR) Flyback topology.
◆Dr. Flyback™ unique Input Power and Switching Frequency one to one mapping, Dr. FlybackTM efficiency is optimized for 100%, 75%, 50%, 25%, 10%, light load and no load consumption.
