Introduction

The MAX20790 is a feature-rich smart power-stage IC designed to work with Maxim’s 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, and supply undervoltage lockout (UVLO). The MAX20790 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 MAX20790 is available in a 12-pin FC2QFN package with an exposed top-side thermal pad (3.25 mm x 7.4 mm).
