The minimum amount of current which must be drawn from an output to maintain output regulation.
Some switching power supplies require a minimum load to stay within their specifications. However, operating them unloaded does no damage.
The minimum load current/power that must be drawn from the power supply in order for the supply to meet its performance specifications. Less frequently, a minimum load is required to prevent the power from failing.
The lowest specified current to be draw on a constant voltage power supply for the voltage to be in a specified range.
The minimum amount of output current required by a SMPS in order to maintain all specifications.
The minimum load current required for a converter to operate within specification.
The least amount of load current or power that needs to be drawn from the power supply in order for the supply to meet its performance specifications.
