Linear Technology Corporation announces the LT3992, a monolithic, dual output step-down switching regulator that delivers up to 3A of continuous output current from each channel. It operates from an ...

A common challenge faced by every power-supply designer is the ability to achieve high-efficiency targets with lower-output-voltage step-down converters. For example, a 3.3-V output-voltage power ...

Experimenting with an HF oscillator, I needed to control the varactor diode voltage in precise increments over a 2V-10V range. A buffered potentiometer was the obvious choice, and connecting two pots ...
