The MAX16602 IC provides a high-density, flexible and scalable solution to power AI cores or Intel® VR13.HC server CPUs. This Maxim controller IC employs coupled inductors and smart power-stage ICs to implement high-efficiency core regulators with 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 can be used to produce regulators with a wide range of current ratings.

The IC’s architecture simplifies design, reduces component count, enables advanced power management and telemetry, and increases energy savings over the full load range. Autonomous phase-shedding is implemented to maintain high efficiency across the entire load range.

Regulator parameters for protection and shutdown can be set and monitored through the serial interface using the PMBus™ protocol. Power-stage faults, input and output voltage, input and output current, input power, and the temperature of each smart power-stage IC are readable over the serial interface. The critical fault retention feature prevents exothermic events after a power-device fault. The smart power-stage ICs communicate with the controller IC through analog and digital signals that are also readable through the registers in the controller IC. Preset and user configurations are programmed in nonvolatile memory (NVM). MTP-programmable NVM circuits allow for seven field modifications.

An integrated 3.3V to 1.8V regulator supports both MAX16602 and power-stage ICs with 1.8V bias supplies. SNS_PS_BIAS monitoring also allows for flexible bias and sequencing.

The MAX16602 is available in a 56-pin, 7mm x 7mm QFN package.

Product Detail

The MAX16602CL8 evaluation kit (EV kit) is a fully assembled and tested surface-mount circuit board that contains all of the components necessary to evaluate the MAX16602 and MAX20790. The MAX16602 is a PMBus™-compatible, multiphase voltage regulator controller for AI cores or Intel® VR13.HC server CPUs. The IC is packaged in a 56-pin, 7mm x 7mm QFN. The controller generates eight pulse-width modulated (PWM) control signals or phases. The EV kit is an 8-phase multiphase synchronous buck converter that uses 2-phase coupled inductors, which reduce the effective inductor value and size without excessive ripple current, thus reducing the required output capacitance and improving transient response.

The EV kit also demonstrates the full functionality of the MAX20790 smart power-stage IC. The IC has monolithic integration and advanced packaging technology that allow high-switching frequencies with significantly lower losses than conventional implementations. There are eight MAX20790 devices for the main output rail.

Warning: The EV kit is designed to operate with 12V input and high current. Follow safe procedures when working with high-current electrical equipment.

Under severe fault or failure conditions, this EV kit can dissipate large amounts of power, which could result in the mechanical ejection of a component or of component debris at high velocity. Operate this kit with care to avoid possible personal injury.
