Eliminate the Guesswork in Controlling EMIA well-defined procedure for predicting EMI in ac-dc power-supply designs and bringing it within regulatory limits saves time and effort versus the trial-and-error methods that designers may be using.... Generate Auxiliary Voltages at Low CostWhen a switching regulator generates the main output voltage, additional regulated outputs may be added using various configurations of coupled inductor or charge-pump circuits.... Expedite Transformer Calculations for FlybacksWhen charging defibrillator capacitors, a novel approach can be used with confidence to come up with a more exacting design, eliminating the cumbersome aspects of many other approaches.... Power Limits Make Hot Swapping More RobustYou need more than just current limiting to ensure that the hot-swap FET stays within its safe operating area under all operating conditions.... Departments Boardrooms and Courtrooms Overshadow EngineeringWhen you were studying in college, your EE professors probably didn't devote much time to the subject of patents. Even less likely would be the prospect of them lecturing on the world of business, and how corporate decisions and intrigues may alter the employment landscape... Data PointsTwo reports issued in recent months from marketing research firms forecast double-digit growth in power IC revenue over the next four to five years... New ProductsLinear Technology's LT3742 is a 100% duty-cycle dual-output stepdown switching regulator dc-dc controller that produces output voltages up to 30 V... Lithium Batteries Are Not Created EqualWithin the lithium family of batteries there are numerous types of chemistries and manufacturing methods, with each offering unique advantages and disadvantages... Current Trends Power Chips Raise the Bar on Operating VoltageBringing higher-voltage capability to rectifiers, FET drivers, controllers and voltage regulators is one more way for semiconductor developers to help their customers achieve a more integrated power design... Multiphase Boost Converter Powers Car Audio AmpAutomotive audio amplifiers often use a boost converter to generate output voltages of 18 V to 28 V (or higher) from the battery... |
