Linear Post Regulators for DC-DC Converters

Focus:

A linear post regulator can reduce the output ripple of a dc-dc converter, while maintaining high efficiency. But changes in temperature and load transients can cause the system to go out of regulation.

What you’ll learn:

• How to interface an isolated dc-dc converter with a low-dropout linear regulator to reduce output ripple
• How to maintain voltage regulation over temperature when using a linear post regulator with dc-dc converter
• How to maintain voltage regulation under load transients when using a linear post regulator with dc-dc converter
