The MAX20754 is a PMBus™-compatible, dualoutput, configurable multiphase power-supply controller for communication and networking applications. The controller is optimized for use with Maxim’s Dual Powertrain™ integrated power stages, which support a wide range of output current and voltage requirements. The controller generates six pulse-width modulated outputs, or "phases." The number of phases per output channel is configurable to support high current requirements and one or two output voltages.This highly versatile controller also includes an integrated switching regulator that supplies power for both the controller and the power-stage devices. The controller features accurate load-current reporting, power-stage temperature monitoring, fault detection, and extensive PMBus-command support. The controller allows the user to save desired PMBus parameters to nonvolatile memory.The controller can be used with traditional discrete inductors, or with coupled-inductor topologies. Coupled inductors reduce the effective inductor value and size without increasing ripple current, reducing required output capacitance, and improving transient response.The MAX20754 uses Maxim’s advanced modulation scheme (AMS) to provide improved transient response and reduce the required output capacitance compared to conventional pulse-width modulation (PWM) control. The AMS can be disabled if strict fixed-frequency PWM operation is desired.ApplicationsASICs, DSPs, and FPGAsCommunication, Networking, Servers, and Storage EquipmentDDR MemoryMicroprocessor Chipsets
