Opt for inductive converter LED drivers
Achieving the desired brightness in mid-size LCD panel applications requires LED drivers to deliver a regulated current to the LEDs across all operating conditions. Typically, two types of LED driver topologies may be used: capacitive charge pumps and inductor-based switching regulators. This article focuses on the inductive converter LED driver circuits delivering between one to six watts of power to the LEDs. Details... more...
Parametric probe cards reduce cost of tests at 45nm
Cascade Microtech has launched two new Pyramid parametric probe cards that allow single-pass high performance DC and RF measurements and reduce the cost of parametric production test for advanced process nodes at 65nm, 45nm and beyond. Details... more...
Why is effective isolation important during test?
According to Yeo Siok Been of Avago Technologies, safety isolation is important for test and measurement equipment to ensure data integrity and to protect test operators. Isolators are selected based on its speed performance and most importantly, based on its insulation levels and ratings to meet required safety standards. Details... more...
