Figure 1: Power stage of the flyback converter (simplified)

Eleazar Falco, FAE, Würth Elektronik eiSos / Editor, Gerhard Stelzer

Isolated flyback converters often use optocouplers in the feedback loop to regulate the output voltage. As part of the compensation circuit, its parameters such as CTR influence the control loop and must be taken into account in the flyback converter design. The flyback converter is an isolated switching power

The Future of Automotive Sophistication

Nick Czarnecki, Melexis

In the past few years, Electric Vehicles (EV) and Hybrid Electric Vehicles (HEV) have started to become a reality. Figures from the International Council on Clean Transportation (ICCT) confirm this; whereas in 2010 the worldwide EV market was negligible, by 2015 over 500,000 electric cars had been sold - and sa

Letting Your Remote Sensor Have A Really Deep Sleep

Binay Kumar Bajaj is a Director, Business Management (Core Products Group) & Michael Jackson, Principal Technical Writer, Maxim Integrated

If you can identify with the feeling of “sleeping with one eye on the clock”, you will know how it prevents you from getting that deep sleep needed to maintain your energy levels, leaving you feeling drained for most of the following day. Key to achieving that all-important deep sleep state is emptying your mi
