A method is provided for supplying power to multiple output channels. Channel control signals are monitored to determine a state for each of the output channels. Each channel control signal is associated with one of the output channels. The energy in a storage element is directed to output channels according to the state of the channel control signals.

Multiple output power supply

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.

Current-regulated power supply with soft-start protection

An over-current protection device is employed to control switching associated with a switched mode power supply to prevent the excessive buildup of current. The device includes a function for relating the switching of the SMPS with a monitored output of the SMPS. This function is selectively modified to ensure the current associated with the SMPS does not exceed a maximum value and does not fall below a minimum value.
