Continuous Tracking Challenges DC-DC Converters

by John Tucker, Applications Engineer, Texas Instruments, Dallas, Power Electronics Technology, Feb 01 2005

Focus:
Applications like termination supplies for DDR memory buses require dc-dc converters that track an external reference voltage with tight tolerances, have fast transient response, and can both sink and source current. A circuit based on the TPS54x72 integrated dc-dc converter IC meets these requirements, needing only resistors capacitors and one inductor to complete the design.
