The new DoE Level VI efficiency standard (DoE 10 CFR Part 430) mandates that no-load power consumption does not exceed 0.100W for external power supplies (EPSs) ranging from 1W to ≤49W, and does not ...

Jetperch has releases a second generation of its Joulescope precision power consumption measurement instrument. Called JS220, it has a huge dynamic range: ±3A max (10A peak) with 500pA resolution over ...

Most seasoned embedded designers are aware that many of the techniques listed in Part 1 can be addressed in the operating system instead of having the design team “reinvent the wheel” with each new ...

Designers frequently turn to advanced power reduction techniques such as power shutoff (PSO) and multi-supply-voltage (MSV) architectures to help reach power consumption targets in advanced technology ...

For power-saving or battery-operated measurement applications, combining a SAR ADC and instrumentation amplifier offers a better solution than a sigma-delta ADC/PGA combo due to its lower power ...

Need to do some real fine power consumption measurements? [Gero Müller] was in that exact situation, and wasn’t happy with the expensive off-the-shelf tools for doing the job. Thus, he built his own.

Ideally switch-mode power supplies would behave like mathematical models. But since they don’t you need to perform thorough characterization and troubleshooting. Fortunately, modern oscilloscopes are ...

Current metrics optimize only 30% of IT emissions ...
