Sequencers, Trackers, & Margining Controllers
Analog Devices sequencers, trackers, and margining controllers provide additional functionality to one or multiple power supplies. Our sequencing controllers allow power supplies to be turned on or off in any order by adding time delays to each supply. In a tracking-based system, a master voltage rail is chosen and all of the lower voltage rails are slaved to its on-ramp or off-ramp. When testing power supplies in an automated PCB test environment, a margining controller allows power supply output voltages to be precisely adjusted up and down by sourcing or sinking current into the feedback node or voltage adjust pin of the power supply. This allows a system to test the correct operation of electrical components at the upper and/or lower power supply voltage limits specified for a given design.
