The MAX15301 is a full-featured, highly efficient, digitalpoint-of-load (PoL) controller with advanced power managementand telemetry features. Unlike PID-based digitalpower regulators, the MAX15301 uses Maxim’s patentedInTune™ automatically compensated, state-space controlalgorithm. The InTune control law is valid for boththe small- and large-signal response and accounts forduty-cycle saturation effects. This eliminates the need forusers to determine and set thresholds for transitioningfrom linear to nonlinear modes. These capabilities resultin fast loop transient response and reduce the number
