Abstract
Abstract An current share controller detects a power converter module having the lowest supply current. That lowest supply current converter module is selected to be the system master. The current share controller is configured such that shared devices within the system can hot-swap capability. An output voltage loop amplifier includes an opto-coupler driver. The voltage loop amplifier compensation is compatible with conventional TL431 shunt regulators. This allows a power supply system to balance supply current between multiple supply modules with an eight pin load balancer configuration.
