Linear Technology LTC4350 Hot Swap Controller Application Note
The document describes the LTC4350 as a tool for developing high availability redundant and load sharing power supply systems. It explains how the controller forces multiple paralleled power supplies to share current by controlling output voltage through active control of the +SENSE pin.
The text focuses on AC analysis and compensation design, detailing requirements for loop bandwidth stability. It provides equations and guidelines for synthesizing current loops with specific Bode plot shapes (0-1 or 0-1,-2) based on the power supply's transfer function characteristics.
