Point of Load (PoL) dc-dc converter modules provide regulated dc power to a wide variety of loads. PoLs are small, efficient and relatively inexpensive, so their ability to provide common powering ...

Selection of a suitable output capacitor plays an important role in switching-converter designs. “Some 99% of the ‘design’ problems associated with linear and switching regulators can be traced ...

Rohm is claiming to have improved load transient response in switching and linear power supplies by modifying the voltage feedback loop. The collection of techniques is intended to reduce the amount ...

There are numerous factors to consider when adding external capacitors to switched-mode power supplies (SMPS). This article will discuss noise, startup, ESR, stability, pre-bias applications, Sense ...

Power management of battery-powered electronic devices is becoming increasingly more important for the microelectronics industry. This white paper details the difference between low dropout (LDO) ...

Designing a circuit is a lot easier on paper, where components have well-defined values, or lacking that, at least well-defined tolerances. Unfortunately, even keeping percentage tolerances in mind ...

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 ...
