Validating power integrity in embedded systems
There are two primary considerations when validating power integrity in embedded systems; the operation of the various power converters and the power distribution system’s integrity. The relative importance of those two considerations depends, in part, on the power system architecture used. In systems with a centralized multiple-output ac/dc power supply, the power supply qualification is […]

The EPC21601 is a laser driver that is controlled using 3.3 […]
How to verify ac/dc power supply performance
Designers specifying ac/dc power supplies are concerned with maintaining performance over a range of input and load conditions and complying with demanding international regulations for efficiency, standby power, harmonics, power factor, safety, and electromagnetic compatibility. Identifying relevant standards and the associated testing requirements is a critical part of that process. This FAQ will review some […]
Basics of AC power measurements
Quantifying the performance of switch-mode power converters is an increasingly important aspect of system design. Systems are often required to meet standards for efficiency, standby power, power factor, harmonic distortion, and more. Switch-mode power converters have large capacitors connected to the ac input, resulting in complex input waveforms. Their performance cannot be analyzed correctly based […]
