  • How to GaN: Gen-4 eGaN FETs

    Posted Oct 30, 2014 By Alex Lidow
    The previous columns in this series discussed the benefits of eGaN® FETs, their potential to improve performance in a variety of applications, and techniques to maximize the performance of GaN transistors. In this installment we will discuss a new family of eGaN FETs that is keeping Moore’s Law alive with significant gains in key switching figures of merit that widen the performance gap with...
  • The P, I, and PI in PID Controllers

    Posted Oct 30, 2014 By Sree Harsha Angara
    In my previous column, I showed bode plots for different types of transfer functions. I also touched on the basic principles of closed loop systems. As a refresher, the gain crossover frequency dictates the speed of the controller, and ensuring a phase margin of around 70 degrees achieves a nice trade-off between the overshoot and speed. Now I’d like to look at how different compensators affect...
  • TRIAC Dimmable LED Driver Design Guide

    Posted Oct 30, 2014 By Fairchild Semiconductor
    This application note provides a practical guideline of TRIAC dimmable LED bulb board design. Passive and active bleeder design guides detail how to maintain latching and holding current without visible flicker. Active damper design improves efficiency by minimizing the count of external components. The input filter design section covers the effect of filter components on PF, THD, and EMI.
