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.

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

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.
