As a review, Renesas' synthetic current control loop architecture implemented on the new generation multiphase controllers offers significant benefits vs. competing solutions. The linear control loop implementation offers a noise free, full bandwidth implementation with one third lower output capacitance vs the competition. This not only delivers total cost of ownership savings, but offers substantial PCB savings, which is becoming a critical factor in modern space-constrained power designs. The full digital implementation enables full device configuration and on-the-fly tuning, achieved using Renesas' intuitive PowerNavigator GUI design. Leveraging sophisticated control of the loop in software speeds up time to market and eliminates board re-work associated with competing solutions in the marketplace.
