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 (3.25mm x 7.4mm).

Applications

  • High Current Multiphase-Voltage Regulators
  • - Networking ASICs
  • - AI and Machine Learning ASICs
  • - Graphics Processors
  • Servers, Workstations, and Enterprise Storage
  • Communications and Networking Equipment
  • AI and Machine Learning

Product Detail

This MAX20754EVKIT8 evaluation kit (EV kit) demonstrates the MAX20754 PMBus™-compatible dual-output multiphase power-supply controller. The controller generates six pulse-width modulated (PWM) control signals, or “phases.” The MAX20754EVKIT8 EV kit is a single-output design, with all six phases assigned to one output. The output uses coupled inductor topologies. Coupled inductors reduce the effective inductor value and size without excessive ripple current, reducing required output capacitance, and improving transient response.

The EV kit also demonstrates the MAX20790 power-stage device; there are six MAX20790 devices, one per phase.

Applications

  • ASICs, DSPs, and FPGAs
  • Communication, Networking, Servers, and Storage Equipment
  • DDR Memory
  • Microprocessor Chipsets

Product Detail

This MAX20754EVKIT7 evaluation kit (EV kit) demonstrates the MAX20754 PMBus™-compatible dual-output multiphase power-supply controller. The controller generates six pulse-width modulated (PWM) control signals, or “phases.” The MAX20754EVKIT7 EV kit is a two-output design, with four phases assigned to Output 1 and the remaining two phases assigned to Output 2. Both outputs use coupled inductor topologies. Coupled inductors reduce the effective inductor value and size without excessive ripple current, reducing required output capacitance, and improving transient response.

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.
