Abstract:
1. A method of monitoring power provided on multiple output channels of a switch mode power supply, comprising the steps of: enabling at least one first output channel to provide a first signal representative of a first output; when the level of the first signal is within a predetermined range of output levels, initiating a first time delay; enabling at least one second output channel to provide a second signal representative of a second output; in the event the second channel is enabled before the expiration of the first time delay, initiating a second time delay when the level of the second signal is within the predetermined range of output levels, and asserting a single status signal when the second time delay expires to indicate that the power provided on the first and second channels is good; and in the event at least one of the first and second signal levels is no longer within the predetermined range of output levels, de-asserting the single status signal to indicate that the power provided on at least one of the channels is no longer good.
