Fully Integrated DC-DC Converters
by Ali Ghahary, Applications Engineering Manager, Enpirion Inc., Bloomsbury, N.J., Power Electronics Technology, Aug 01 2004
Focus:
By developing lateral MOSFETs with fast rise and fall times, Enpirion has developed a monolithic buck regulator IC that operates at switching frequencies in the 5 to 10 MHz range, anabling co-packaging of regulator chip and an inductor.
What you’ll learn:
- How to understand the concepts underlying the co-packaging of a buck regulator and inductor
- How to understand the concepts underlying multi-meghertz switching in a buck regulator IC
- How to understand the concepts underlying operation of a power-supply-in-package (PSiP) device
