Any boost-converter design will have a practical limit to how much it can step up a voltage from input to output. Pulse-width modulation (PWM) controllers have timing limits that restrict the minimum ...
The LTC2645 converts pulse-width-modulation (PWM) input signals to 12-bit accurate, stable buffered voltage outputs in less than 8 µs, thus removing the ripple and delay often plaguing analog filters.
A recent Design Idea, “Three discretes suffice to interface PWM to switching regulators,” demonstrated one way to use PWM to control the output of a typical switching voltage regulator. There were ...
For the PDF version of this article, click here. Over the years, power supply designers have been persuaded that current mode is superior to its voltage-mode counterpart. As a result, the major PWM ...
