The control loop of a POL module regulates the output voltage. The conventional approach is to ensure that the power supply remains stable under a very wide range of expected load switching events and external capacitance. The tunable loop is a patent-pending technology that allows the user to easily and simply modify the internal control loop of the power supply, allowing it to adapt to the specific application needs through the use on an external Rtune/Ctune combination. The result is a significant reduction in both cost and space. Where space and cost are not primary design drivers, then the tunable loop provides a significant performance boost.
