The MAX20747 is a feature-rich smart power-stage IC designed to work with Analog Devices’ controllers to implement a high-density multiphase voltage regulator. Multiple smart power-stage ICs plus a controller provide a compact synchronous buck converter that includes accurate individual phase current and temperature reporting through PMBus™. These smart power-stage devices include fault-protection circuits for overtemperature, VX short, I/O open/short, supply undervoltage lockout (UVLO), and main power-supply overvoltage lockout (OVLO). The MAX20747 immediately shuts down on fault detection, communicating the Fault_ID to the controller.
Monolithic integration and advanced packaging technology allow high-switching frequencies with significantly lower losses than conventional implementations. Phase shedding and discontinuous conduction modes (DCM) optimize efficiency over a wide range of load currents. An external 1.8V is required for IC bias.
The MAX20747 is available in a 4mm × 6mm, 34-pin FCLGA package.
