Testing considerations for USB and USB-PD
Designers integrating USB Type C and USB4 into their products confront several challenges to ensure interoperability and compliance. Compared with previous generations, the latest USB specifications are more demanding due to higher power and more complex power profiles, higher data transmission speeds, and more functionality in general. To address these challenges, test engineers must start […]
High-voltage superjunction MOSFETs deliver 10 m Ω RDS(on)
In applications where MOSFETs are switched at low frequency, high-power product designs must meet several key characteristics: They have to minimize conduction losses, provide optimal thermal behavior, and enable more compact and lighter systems – all while maintaining the highest quality at a low cost. To meet these requirements, Infineon Technologies AG is enhancing the […]
AC-DC power supply module meet challenging and space-critical applications
XP Power has announced the availability of a new range of low profile, half brick, baseplate cooled AC-DC power supplies which require no external circuitry for operation or EMC compliance. Models in the new ASB75 series offer compact, fanless power with baseplate cooling for applications such as information technology equipment (ITE), Internet of things (IoT), […]
What you should know about Thunderbolt 3, 4, 5 and USB
With Thunderbolt 3 well established, Thunderbolt 4 coming onto the market, and Thunderbolt 5 in the early stages of being defined, it’s important that designers understand the similarities and differences between the various flavors of Thunderbolt and how they compare and contrast with USB. Intel designed thunderbolt technology in cooperation with Apple to support new […]
DC-DC buck controller integrates active EMI filter
Texas Instruments introduced a new family of synchronous DC/DC buck controllers that enable engineers to shrink the size of the power-supply solution and lower its electromagnetic interference (EMI). Featuring an integrated active EMI filter (AEF) and dual-random spread-spectrum (DRSS) technology, the LM25149-Q1 and LM25149 enable engineers to cut the area of the external EMI filter […]
Richardson Electronics highlights new UnitedSiC FET-Jet calculator
The FET-Jet calculator by UnitedSiC is a tool for finding the most optimized SiC device in the early stages of power design. UnitedSiC recently released the FET-Jet calculator, a tool that helps engineers in the early design stage find the ideal SiC device. With no registration required, the calculator starts with three application functions, ac-dc, […]
USB proliferation of capabilities and compatibilities
USB4 represents a significant change from past standards from the USB Implementers Forum (USB-IF). USB4 is based on the Thunderbolt 3 protocol. Support of Thunderbolt 3 interoperability is required on all ports for USB4 docks. It is required for downward-facing ports on hubs and is optional for USB4 hosts and peripheral devices. Like Thunderbolt, USB4 […]
