Under certain environmental conditions such as high moisture and elevated temperatures or in the presence of ionic contamination, a slight amount of surface oxidation has been found to form on the surface of a small percentage of IHLP inductors.
The following report contains construction details, the results of analysis,...



Utilizing embedded microcontrollers for industrial applications requires special attention given the harsh and noisy environment. Going from a supply voltage as low as +1.5V or +3.3V to the +24V industrial world requires careful design decisions and dedicated solutions to achieve safe and reliable operation.
The following...



Like its predecessor, the Peripheral Component Interconnect (PCI), PCI Express is becoming a ubiquitous system interface. Unlike PCI, PCI Express adopts a Serializer/Deserializer (SERDES) interface to provide users with the scalability required for future applications. As system bandwidths increase, more applications are...



System designers are faced with continual pressure to meet their development schedules, and need to implement designs with minimal effort and risk while maintaining maximum flexibility. By using a programmable-based approach instead of several discrete devices or Application Specific Standard Products (ASSPs), designers...



This paper describes a method for reducing the power consumption of sensor systems by utilizing the standby functions of a microcontroller (MCU). In concrete terms, the frequency of sensor measurements is reduced, and the system is kept in the standby condition for as long as possible. Furthermore, abnormality detection...



DC-DC converter designers can achieve higher power density at lower power levels by using forward converters with synchronous rectification and gallium nitride transistors. One very typical application is a 26 W, 48 V to 5 V , Power over Ethernet Powered Device (PoE-PD).
A simplified forward converter schematic for...



Adding security to a device costs extra money, time, power consumption and makes everything worse. The only reason for adding security to a device is the need to improve marketing – security components help to sell more products. To participate in the evolution of Industry 4.0, the Internet of Things and cloud technologies...



In this white paper EPC continues our exploration of optimization issues and look at the impact of dead-time on system efficiency for eGaN® FETs and MOSFETs.
Previously published articles showed that eGaN FETs behave similarly to silicon devices and can be evaluated using the same performance metrics....



High-voltage power management ICs, such as TI’s LM5000 series of integrated controllers and regulators, can simplify the design of high-voltage power management solutions
This paper presents various application scenarios where high-voltage capability up to 100V is required and explains how high-voltage power...



As electronic systems continue to trend toward lower voltages with higher currents and as the speed of contemporary loads continues to increase, the power systems designer is challenged to provide small, costeffective and efficient solutions that offer the requisite performance.
Vicor’s new Factorized...



For applications requiring high power density and high power, but not requiring electrical isolation, the buck converter has been the workhorse topology for many years. Improvements in buck converters over the past few years have been limited by the power MOSFET’s sedate switching speeds.
In this paperEPC...



To achieve some of the ambitious Key Performance Indicators of 5G enhanced Mobile Broadband, semiconductor devices for 5G infrastructure need to empower reliable multi-user MIMO (MU-MIMO) functionality at mmWave frequencies with larger channel bandwidths. 5G base stations achieve this spatial multiplexing by employing...
