This reference document describes a built-and-tested, GreenPointTM solution for a Notebook AC-DC adapter. The reference design circuit consists of one single-sided printed circuit board designed to fit into a standard notebook adapter plastic case. As shown in figure, the reference design offers a simplified notebook adapter power supply solution, where by judicious choice of design tradeoffs, optimum performance is achieved at minimum cost. This reference design document provides a solution to address the design challenges brought about by different regulations: compliance with IEC1000-3-2, with requirements for standby power reduction and active mode energy efficiency increase at a reasonable cost.
