The MAX16602 IC provides a high-density, flexible and scalablesolution to power AI cores or Intel® VR13.HC server CPUs.

This Maxim controller IC employs coupled inductors andsmart power-stage ICs to implement high-efficiency coreregulators with enhanced transient response and lowquiescentcurrent. An additional single-phase output generatesthe VSA rail in the system using a single-phase smart powerstage. The complete circuit is a highly efficient (8+1)multiphase synchronous buck converter with extensivestatus and parameter-measurement features. The controlleralso supports PWM paralleling to control up to 16 phases. Asingle, scalable PCB design with appropriate smart powerstageIC selection can be used to produce regulators with awide range of current ratings.

The ICs architecture simplifies design, reduces componentcount, enables advanced power management and telemetry,and increases energy savings over the full load range.

Autonomous phase-shedding is implemented to maintainhigh efficiency across the entire load range.

Regulator parameters for protection and shutdown can beset and monitored through the serial interface using...
