High-Accuracy Current-Sense Amplifier Enables Current Sensing
and Current Sharing

Abstract: Current sharing between DC/DC converter modules enables several modules to be paralleled. In
recent years, tight tolerances for current sharing have made discrete current-sense circuit designs a formidable
challenge. This application note describes a low-cost, space-saving and accurate current sensing and sharing
scheme using MAX4372.


Current sharing between DC/DC converter modules is a very important system parameter in ensuring reliable
operation. In recent years, the toleran
