User Manual
This document describes the features of the LTC4350 Hot Swap™ and load share controller, a powerful tool for developing high availability redundant and load sharing power supply systems. It can work with supplies with any output stage topology, including output stages using synchronous rectification.
User Manual
The LTC4350 is a load share controller that allows systems to equally load multiple power supplies connected in parallel. The output voltage of each supply is adjusted using the SENSE+ input until all currents match the share bus. The LTC4350 also isolates supply failures by turning off the series pass transistors and identifying the failed supply. The failed supply can then be removed and replaced with a new unit without turning off the system power. The LTC4350 is available in a 16-pin narrow SSOP package.
