Abstract
A current-regulated power supply provides soft-start protection to prevent the generation of large in-rush currents. The current-regulated power supply includes a current regulation module that operates in either a soft-start mode of operation or a normal mode of operation and a mode selection module that makes mode of operation determinations. In particular, mode-selection module monitors the load current supplied to the attached load and maintains the current-regulation module in the soft-start mode of operation until the monitored load current exceeds a threshold value, at which time the mode-selection module causes the current regulation module to operate in the normal mode of operation.
