Abstract: 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.

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.

Abstract: 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.

Abstract: A lighting system includes at least first and second light sources providing first and second colors of light. Control circuitry is operatively coupled to the first and second light sources, and is configured to control the first and second light sources relative to one another to provide a color point that is linearly controlled to approximate a non-linear target lighting behavior in the CIE 1931 color space.

Abstract: A power supply includes a current supply, a plurality of output channels, and a controller. Each of the output channels has a load and a channel switch with a reference voltage. All of the channel switches are referenced to the same reference voltage.
