Hot Swappable Load Share Controller

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.
