The MAX16625/MAX16627 are feature-rich low input voltage smart power-stage ICs 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 MAX16625/MAX16627 immediately shut 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 MAX16625 is available in a standard (3.25mm x 7.4mm) 12-pin FC2QFN package, while the MAX16627 is in a narrow (3.05mm x 7.25mm) 12-pin FC2QFN package. Both packages have an exposed top-side thermal pad.
