AN-1950 Silently Powering Low Noise Applications (Rev. A)


This application report explains how to implement a low noise switch mode power supply solution. It introduces the sources of noise and explain how to minimize them. A big factor in noise generation and propagation is the printed circuit board layout. Important basics are discussed. Circuit measurement techniques are also explained to guide a design engineer towards a low noise but efficient solution.
