Analog Devices / Maxim Integrated MAX16602 VR13.HC & AI Cores Voltage Regulator

Analog Devices MAX16602 VR13.HC and AI Cores Voltage Regulator provides a high-density, flexible, and scalable solution to power AI cores or Intel® VR13.HC server CPUs. The MAX16602 uses coupled inductors and smart power-stage ICs to implement high-efficiency core regulators. This Analog Devices regulator has enhanced transient response and low quiescent current. An additional single-phase output generates the VSA rail in the system using a single-phase smart power stage. The complete circuit is a highly efficient (8+1) multiphase synchronous buck converter with extensive status and parameter-measurement features. The controller also supports PWM paralleling to control up to 16 phases. A single, scalable PCB design with appropriate smart power stage IC selection is used to produce regulators with a wide range of current ratings.
