This Application Note was written to provide insight into the one time requirement for ‘type’ testing of power supplies by the safety agency or manufacturer. It will assist in the interpretation of requirements for this testing and provide broad guidelines on exactly what is required of the manufacturer in...

The following white paper uses a typical off-the-shelf isolated DC-DC converter to demonstrate how an active filter will not only provide superior filtering, as compared to the passive approach, but will also provide a simple turnkey solution to meet challenging transient response requirements.
The performance...
The digital signage market is experiencing rapid growth. Organizations across a wide range of industries are making large investments in the content, source machinery and displays that comprise digital signage systems. The choice to protect these investments from power problems is crucial—yet frequently overlooked....
The semiconductor shortage has hindered production across industries, including the home appliance and telecommunications sectors.
While the chip industry has dozens of new factories in its sights, they will take years to build, meaning no relief anytime soon. Meanwhile, manufacturing equipment scarcity–caused,...

Even though the eGaN FET was designed and optimized as a power-switching device, it also exhibits good RF characteristics. The smallest 200 V eGaN FET, EPC2012, was selected for RF evaluation and should be viewed as a starting point from which the RF characteristics of future eGaN FET part numbers can be optimized for...
A sound discrete power supply design requires a high level of expertise and is timeconsuming to design. Power modules offer an easier path, in a ready-to-use plug-and-play reliable design for rapid prototyping or end use.
A new generation of power modules on the market today offers greater integration, for a smaller...
While almost every power-supply engineer intimately knows and understands the lab setup for measuring efficiency, there are many important nuances that must be considered when measuring the efficiency of a device with ultralow quiescent current (IQ). For a device that consumes less than 1 µA, the circuit’s...
It is absolutely necessary to use code-compliant power strips in patient care vicinities to minimize the risk of potentially harmful shocks. UL 60601-1 power strips with fault protection are uniquely suited for standalone use in patient care vicinities, but misleading marketing and labeling makes it difficult to distinguish...
ICs with on-board oscillators requiring low frequency fundamental crystals are commonplace but now IC frequency multipliers require the higher frequencies of third overtone crystals. Compared to its fundamental implementation however the third-overtone (3OT) crystal oscillator is more complex, with different crystal characteristics...
If you supply products for GSA Schedules and other government contracts, those products must comply with the federal Trade Agreements Act (TAA). Failure to comply with TAA can lead to bid award cancellation, multimillion-dollar fines and exclusion from federal contracting.
Sourcing TAA-compliant IT products presents...
The more successful a gate driver is in reducing power-up and power-down times, the bigger the headache for accurate measurements. Both choosing the right probe and optimizing the probing technique are significant factors in improving measurement accuracy.
This whitepaper provides guidelines.
Fractional turn transformers are not a new idea but it's not a concept that appears to have been applied to AC/DC power supplies in the past. For multiple output power supplies in particular it offers some significant advantages in terms of saving space, cutting cost and improving efficiency.
The challenge...
Modern power architectures are advancing miniaturization of semiconductors and other discrete devices. These advancements require migrating to more progressive design topologies to increase density and efficiency. This shift in developing new technology is transforming all facets of the design process. At the same time,...
