In order to meet market requirements, power AC-DC adapters for notebooks and tablets need to be small, thin, lightweight, and provide excellent EMI performance as well as ultra-low, highly efficient standby power, regardless of the load conditions. A typical high-efficiency design includes a flyback stage with synchronous rectification and for higher power, a Power Factor Corrector (PFC) working in Transition Mode (TM) followed by a flyback, forward or half-bridge LLC resonant stage with synchronous rectification.
