Power AC-DC adapters for notebooks and tablets need to be as small, thin and lightweight as possible while providing ultra-low stand-by power with high efficiency at all load conditions and excellent EMI performance.

A typical high-efficiency design includes a power factor corrector (PFC) working in Transition mode (TM) followed by a fly-back, forward or half-bridge LLC resonant stage.

We have a broad range of high-voltage MDmesh™ and low-voltage STripFET power MOSFETs as well as standard and field-effect rectifiers (FERD). Our offers also includes a range of PFC, PWM primary controllers and single-chip combo controllers as well as a comprehensive set of hardware and software evaluation and development tools including reference designs to help develop high-efficiency, compact adapters.
