Engineers can register for the one-hour session on the TI website.
Webcast panelists will address the need to move away from using a traditional three-terminal linear regulator as system voltages decrease and currents increase in system applications.
While this technique typically involves placing the regulator on the PCB, switching regulars are quite different.
These new regulators typically leverage high-frequency switching techniques to convert one voltage level to another.
The switching techniques create high voltage and current slew rates that interact with PCB parasitics and can cause significant performance problems.
The expert panellists will discuss proper layout techniques for avoiding design pitfalls.
During the lab segment, Klein and Garvey will demonstrate how to minimise parasitic components when laying out a PCB.
They will discuss which traces create noise and which traces are susceptible to noise within a switching regulator.
In addition, they will provide engineers with basic knowledge on the layout of a switching regulator, how to place and route the power train and how to control it.
This will help the engineers avoid the most common problem of noise when using a switching regulator.
