One of the simplest voltage regulator control strategies is the hysteretic regulator. This control methodology simply turns a switch on when the output voltage is below a reference and turns the ...
Output voltage ripple plagues various types of portable electronics products. Voltage ripple is an unwanted artifact generated by switching regulators, the dc/dc converters which supply power to board ...
The purpose of this article is to walk through the steps of implementing a ripple injection circuit for constant on-time POLs. It covers how to connect the circuit and then how to calculate the values ...
In an example DAC application using Actel’s CorePWM IP DirectCore in low-ripple DAC mode (block diagram, Figure 2, main article), PWM output is averaged to a varying dc voltage. At reset, the PWM duty ...
Members can download the PDF ebook. Recently, I helped a guy who needed low output ripple on a power supply. His 1000-V output required low, submillivolt ripple. I designed a couple of circuits for ...
Step-down (buck) voltage regulators have long been the preferred DC-DC conversion electronic workhorse thanks to their inherently high efficiency. Only in buck mode the current is directed to the ...
