APEC: TI thinks laterally to make ac-dc chip with 15mW stand-by

Texas Instruments has used everything except the standard inductive step-down solution to make an ac-dc power supply with 10mW no-load performance, and 15mW light load drain (150nF mains series cap). “This device achieves the best balance between high efficiency and ultra-low noise while shrinking power-supply size, it claims, with some justification – although it does ...

Coventry has best mobile coverage

Coventry is the top-performing UK city for overall mobile performance in the second half of 2018, says RootMetrics. With one of the smallest populations out of the 16 cities tested, Coventry recorded outstanding results in the categories of overall performance, network reliability, network speed, data performance and call performance. Leicester logged impressive scores in testing, ...

TI isolated gate drivers integrated sensing for IGBTs and SiC MOSFETs

TI introduced several new isolated gate drivers that provide monitoring and protection for high-voltage systems. The devices are claimed to be the first to offer integrated sensing features for IGBTs and SiC MOSFETs to simplify designs and enable greater system reliability in applications operating up to 1.5 KVRMS. With integrated components, the devices provide fast ...
