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 […]
