Ask a power converter designer what they want from a semiconductor switch and the answer might be something like: “Low on-resistance, high off-resistance, and the fastest possible transition between the two states”. The idea of course, ...
We very often see flocks of birds perched in trees, on rooftops, on local power line wires, and even on radio antennas. Figure 1. Birds often perch on antennas. However, I have noticed that I never see birds coming to rest on high-tension power ...
Question: Where do I connect the grounds of switching regulators? Answer: How should you proceed with a switching regulator with an analog ground (AGND) and a power ground (PGND)? This is a question asked by many developers designing a switching ...
This publication details circuitry and applications considerations for the LT1533 low noise switching regulator. Eleven DC/DC converter circuits are presented, some offering 100µV output noise in a 100MHz bandwidth. Tutorial sections detail ...
This application note describes the unique operating characteristics of the LT1005 and describes a number of useful applications which take advantage of the regulator's ability to control the output with a logic control signal.
This application note describes a number of enhancement circuit techniques used with existing 3-terminal regulators which extend current capability, limit power dissipation, provide high voltage output, operate from 110 VAC or 220 VAC without the ...
Bob Sheehan Electronic Design Ascertaining the relationship between bandwidth and response in power supplies isn’t easy, but this Idea for Design presents a measurement approach that helps ease the process. It’s normal to assume that ...
Haifeng Fan, Texas Instruments Introduction The demand for boost regulators has increased recently due to emerging applications in automotive, industrial and consumer marketplaces. Examples of new applications include emergency call (eCall) ...
Haifeng Fan, Texas Instruments Part 1 Non-synchronous versus synchronous rectification Figure 7. Synchronous boost regulator. The DC/DC switching regulators shown in the previous examples are all non-synchronous in which a rectifier diode is used. ...
Introduction Battery-powered electronics poses multiple challenges to the power system engineer. At a theoretical level, the battery related circuitry (before DC/DC conversion) may be divided into four functions: power selection, charging (for ...
