This evaluation 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 MAX20754 evaluation kit (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 MAX20766 power-stage device. There are six MAX20766 devices, one per phase.
