The MAX20856 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™. This smart power-stage device includes fault-protection circuits for overtemperature, VX short, I/O open/short, supply undervoltage lockout (UVLO), and main power-supply overvoltage lockout (OVLO). The MAX20856 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. The MAX20856 integrates an internal LDO, simplifying bias generation for applications that do not have 1.8V available.
The MAX20856 is available in a 41-pin FC2QFN package.
