Analog Devices / Maxim Integrated MAX20790 Smart Power-Stage IC
Analog Devices MAX20790 Smart Power-Stage IC is designed to work with ADI controllers to implement a high-density multiphase voltage regulator. The MAX20790 features multiple smart power-stage ICs plus a controller that provides a compact synchronous buck converter. It includes accurate individual phase current and temperature reporting through PMBus™. These Analog Devices smart power-stage ICs include fault-protection circuits for overtemperature, VX short, and supply under-voltage lockout (UVLO). The MAX20790 immediately shuts down on fault detection, communicating the Fault_ID to the controller.Features
