Synchronous DC-DC Buck Converter Using 2-step Delay Locked Loop (DLL), and Compensation Method of Propagation Delay Time

Sungkyunkwan University Foundation for Collaborate Business Team, Kyunggido, Korea

TECHNOLOGY SUMMARY

This DC-DC buck converter which allows an inductor-less and capacitor-less state, the efficiency is considerably reduced by a propagation-delay problem due to a high frequency.This technology is to compensate the propagation delay using a 2-step delay locked loop(DLL) and thus to design the high efficiency DC-DC buck converter.

Primary Application Area: Electronics, Sensors & Communications

Technology Development Status: Proven Manufacturability

Technology Readiness Level: TRL 5

FIGURES OF MERIT

Value Proposition: This technology can effectively prevent the propagation delay which occurs while the switching frequency of the DC-DC buck converter for implementing the inductor-less and the capacitor-less is increased, can provide the high efficiency, and also can realize a cost effective structure through the low power and the small surface area.
