SYSTEMS AND METHODS OF SYNCHRONOUS RECTIFIER CONTROL

Title:

SYSTEMS AND METHODS OF SYNCHRONOUS RECTIFIER CONTROL

Document Type and Number:

WIPO Patent Application WO/2011/050084

Kind Code:

A3

Abstract:

Systems and methods for synchronous rectifier control are provided. A synchronous rectifier includes parasitic drain inductance and parasitic source inductance. Compensation inductance is introduced to offset the effects of parasitic inductance. Compensation inductance may be formed from the trace inductance on the semiconductor die. In certain semiconductor packages, the parasitic inductance may be substantially fixed such that the layout can be modified to generate fixed compensation inductance.
