Fairchild High Voltage Products are Integral to the Auto Sector 8 May 2013 | 07:37 pm
While the debate on EV/HEV tax credits, battery technology and infrastructure has been a constant over the last decades, high voltage technology for Automobiles remains a key enabler for advanced appl...
A Part of Semiconductor History Traveling the Cosmos 5 Feb 2013 | 04:35 am
During the 1970s – while Fairchild Semiconductor was launching a few first in the industry devices – it was also becoming a legendary part of United States (as well as human-kind) history. In 1977, NA...
Higher Efficiency with Space Vector PWM Control in a BLDC Motor 31 Oct 2012 | 10:45 pm
Research shows that as much as 70 percent of the total electricity consumed by the average modern household goes to power motors in appliances like refrigerators, washing machines, air conditioners, f...
Quasi-Resonant Switching in a 30W Power Supply 25 Oct 2012 | 09:12 pm
For switched-mode power supplies operating at low power levels, a flyback topology typically offers the best efficiency, but there is a risk of potentially high voltage stress on the switch. Using a q...
The Next Step in Phototransistor Optocouplers 23 Oct 2012 | 11:30 pm
Phototransistor optocouplers have continued to evolve since they were first introduced 40 years ago, and remain popular even now. The versions most widely available today use an infrared light emittin...
Up in Smoke: The Gnarliest and Most Effective Ways to Destroy a MOSFET 17 Oct 2012 | 10:53 pm
Dear Dr. Engleberry: This might seem like an odd request, but I am trying to duplicate a field failure and I need to destroy a MOSFET in the harshest, gnarliest and most-nastiest possible way. What c...
650V IGBT for Solar Inverters: Higher Blocking Voltage without Losing Efficiency 9 Oct 2012 | 10:47 pm
Designers of photovoltaic (PV) inverters have found that using an IGBT with a high blocking voltage can help increase reliability in several ways. A higher blocking voltage can increase the margin on ...
Which Power Switching Topology is Right for You? Balancing Efficiency and Thermal Design in LED Lighting 13 Aug 2012 | 11:15 pm
In LED lighting, matching the driver topology to the power level can be challenging. There are a number of topologies to choose from, but which one will give the right balance of size, performance, an...
A Better Retro-fit LED Topology PSR Flyback with Built-in PFC for a Compact, Reliable Design 19 Jul 2012 | 10:09 pm
Using high-brightness, high-efficiency LED lights in new construction promises to help save energy in the future, but there are immediate gains to be had from using LEDs in retrofit bulbs. Putting a n...
