Regulatory creepage and clearance requirements are increasingly affecting mainstream designs; understanding and meeting them is a complicated, multifaceted process. The final part of this article looks at an IC pair specifically designed for an enhanced creepage and clearance value, tools for helping with design, and also provides some “pre-electronics” perspective on the subject. Q: Are […]

SiC gate driver benefits traction inverters for EVs
Texas Instruments debuted a highly integrated, functional safety-compliant, isolated gate driver that enables engineers to design more efficient traction inverters and maximize electric vehicle (EV) driving range. The new UCC5880-Q1 reinforced isolated gate driver offers features that enable EV powertrain engineers to increase power density and reduce system design complexity and cost while achieving their […]
APEC 2023 round-up
The Applied Power Electronics Conference (APEC) has grown over the course of a few decades to be the leading conference in North America for power electronics professionals. This past month, March 19th to the 23rd, in Orlando, APEC returned to share the latest trends, technologies, and opportunities in power electronics with industry and academia alike. […]
Power supply ICs come in rad-hard plastic packages
Texas Instruments announced an expansion in its portfolio of space-grade analog semiconductor products in highly reliable plastic packages for a diverse range of missions. TI developed a new device screening specification called space high-grade in plastic (SHP) for radiation-hardened products and introduced new analog-to-digital converters (ADCs) that meet the SHP qualification. TI also introduced new […]

Enabling a do-it-yourself hot-swap circuit design using a hybrid architecture
By Durga Praveen G and Rakesh Panguloori, Texas Instruments There is unprecedented demand for highly available and redundant systems to offer the best user experience. For example, in communications, banking, and industrial automated systems, any amount of system downtime could potentially lead to lost customers. The implementation of a hot-swap circuit at the input of […]
How to gauge LED flicker
A few years ago, back when ordinary LED bulbs still sold for north of $10 a piece, there was a great brouhaha about LED light flicker. Light flicker can certainly be dangerous. Sufficiently intense flicker at between 3 and 70 Hz can cause epileptic seizure in a small percentage of the population. And flicker that […]
Relays designed for higher reliability in isolated high-voltage environments
Building on more than two decades of experience developing new isolation manufacturing technologies and integrated circuits (ICs) for high-voltage systems, Texas Instruments introduced new portfolio of solid-state relays, including automotive-qualified isolated drivers and switches, that deliver industry-leading reliability to help make electric vehicles (EVs) safer. The new isolated solid-state relays also provide the smallest solution […]
Buck/boost converter boasts super-low quiescent current, targets battery powered apps
Texas Instruments introduced a new bidirectional buck/boost converter with an ultra-low quiescent current (IQ) of 60 nA – one-third the IQ of competing boost converters. The TPS61094 buck/boost converter integrates a buck mode for supercapacitor charging while providing ultra-low IQ, enabling engineers to extend battery life by as much as 20% when compared to commonly used hybrid-layer […]
