When you can use Spice and it’s variants, when you can’t

December 17, 2020 By dherres

It has been a long time since it was practical to breadboard even moderately complex IC designs to evaluate them prior to manufacture. This is particularly true because of subtle parasitic and characteristic impedance effects that rear their ugly head in the frequency ranges of many modern circuit designs. That is the rationale for Spice […]

Low-noise dc/dc switching regulators host integrated ferrite-bead compensation

October 22, 2020 By Redding Traiger

Texas Instruments introduced a new family of low-noise DC/DC switching regulators with integrated ferrite-bead compensation. The TPS62912 and TPS62913 offer low noise of 20 µVRMS for frequencies ranging from 100 Hz to 100 kHz and ultra-low output-voltage ripple of 10 µVRMS, giving engineers the ability to remove one or more low-dropout regulators (LDOs) from their designs, […]

Ethernet PHY chip transmits 10 Mbps signals up to 1.7 km

October 8, 2020 By Redding Traiger

Texas Instruments introduced a new Ethernet physical layer (PHY) capable of transmitting 10-Mbps Ethernet signals up to 1.7 km through a single pair of twisted wires. The extended cable reach of the DP83TD510E is 1.5 km more than the 200-m requirement of the Institute of Electrical and Electronics Engineers (IEEE) 802.3cg 10BASE-T1L single-pair Ethernet specification. […]

Hall-effect current sensors first with zero drift

July 8, 2020 By Aimee Kalnoskas

Texas Instruments introduced the industry’s first zero-drift Hall-effect current sensors. The TMCS1100 and TMCS1101 enable the lowest drift and highest accuracy over time and temperature while providing reliable 3-kVrms isolation, which is especially important for AC or DC high-voltage systems such as industrial motor drives, solar inverters, energy-storage equipment and power supplies. Ongoing demand for higher […]

DC-dc converter ICs can be stacked to deliver 160 A

March 10, 2020 By Aimee Kalnoskas

Texas Instruments introduced a new 40-A SWIFTTM DC/DC buck converter, offering first-of-its-kind stackability of up to four integrated circuits (ICs). The TPS546D24A PMBus buck converter can deliver up to 160 A of output current at an 85°C ambient temperature – four times more current than competing power ICs. The TPS546D24A has the highest efficiency of any 40-A DC/DC converter, […]
