Buck Converter Losses Under the Microscope

Focus:

Parasitic inductances associated with MOSFET packaging and pc board traces contribute to power losses while limiting switching frequencies in synchronous buck converters used in VRM designs.

What you’ll learn:

• How to analyze the impact of parasitic inductances (MOSFET package lead inductance and pc board trace inductances) on synchronous buck converter efficiency and switching speeds
• How to noninvasively measure current in high-frequency buck converters
