The IR3513Z Control IC provides overall control of a scalable number of phases along with an internal gate driver, current sense/sharing, and PWM. This allows the IR3513Z to implement a stand-alone single-phase regulator or interface with additional Phase ICs to develop a power solution with any number of phases. With this arrangement, the final solution requires only 1 IC per phase to deploy 1 to X phases. Other approaches require a control IC plus 1 to X driver ICs or scalable "all-in-one" ICs that do not utilize all IC pins or circuitry leading to increased solution cost and size.
