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.

ST offers a broad range of high-voltage MDmeshâ„¢ and low-voltage STripFET Power MOSFETs as well as standard and Field-Effect Rectifiers (FERD) to support the design of highly efficient, compact adapters. Our product portfolio also includes a range of PFC, PWM primary controllers and single-chip combo controllers, synchronous rectification controllers as well as a comprehensive set of hardware and software evaluation and development tools, including reference designs.
