Description

The MAX20766 is a feature-rich smart slave IC designed to work with Maxim’s seventh-generation controller to implement a high-density multiphase voltage regulator. Up to six smart slave ICs, plus a controller IC, provide a compact synchronous buck converter that includes accurate individual phase-current and temperature reporting through SMBus/PMBus™. This smart slave device includes protection circuits for overtemperature, VX short, and all power-supply UVLO faults. If a fault is detected, the slave IC immediately shuts down and sends a fault signal to the controller IC.Monolithic integration and advanced packaging technologies allow practical per-phase, high-switching frequencies with significantly lower losses than alternative implementations. Smart slave ICs are designed to support phase shedding and DCM modes for efficiency optimization over a wide range of load currents. High per-phase current- capability designs with low COUT enable a design with fewer phases and a smaller footprint.The MAX20766 is available in a 16-pin FCQFN package with exposed top-side thermal pads. Top-side cooling improves heat transfer to ambient and reduces PCB and component temperatures.
