MAX20751Multiphase Master with PMBus Interface and Internal Buck Converter | Evaluation Boards | 3 | Active | The MAX20751 PMBus™-compliant multiphase master IC, with extensive status and parameter monitoring, is capable of driving up to four smart-slave integrated power devices.Utilizing Maxim’s smart-slave ICs, the device provides a high-density and flexible solution that can be tailored to a range of power loads used in communication equipment. Proprietary-coupled inductors, recommended to reduce the effective inductor value without excessive ripple current, results in improved transient response and reduction in the number of output capacitors required.The device incorporates current reporting, temperature monitoring, fault detection, and PMBus support. Overcurrent and overtemperature faults are detected by the individual smart slaves and faults communicated through the master IC. The highest junction temperature is reported, both before and after smart-slave regulation.The device features an integrated switching regulator that can optionally be used to supply the VDDrail for the master controller and smart-slave devices to reduce the power-rail requirements and simplify the regulator design.ApplicationsCommunication, Networking, Servers, and Storage Equipment: ASICs, Memory VDDQ, Microprocessor Chipsets, and other High-Current Digital ICs |
MAX20754Dual-Output, Configurable Multiphase Power-Supply Controller with PMBus Interface and Internal Buck Converter | Evaluation Boards | 9 | Active | 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 |
MAX20766Smart Slave IC with Integrated Current and Temperature Sensors | Full, Half-Bridge (H Bridge) Drivers | 2 | Active | The MAX20766 is a feature-rich smart slave IC designed to work with Maxim’s seventh-generation controller to implement a high-density multiphase voltage regulator. Up to six smart slave ICs, plus a controller IC, provide a compact synchronous buck converter that includes accurate individual phase-current and temperature reporting through SMBus/PMBus™. This smart slave device includes protection circuits for overtemperature, VX short, and all power-supply UVLO faults. If a fault is detected, the slave IC immediately shuts down and sends a fault signal to the controller IC.Monolithic integration and advanced packaging technologies allow practical per-phase, high-switching frequencies with significantly lower losses than alternative implementations. Smart slave ICs are designed to support phase shedding and DCM modes for efficiency optimization over a wide range of load currents. High per-phase current- capability designs with low COUTenable a design with fewer phases and a smaller footprint.The MAX20766 is available in a 16-pin FCQFN package with exposed top-side thermal pads. Top-side cooling improves heat transfer to ambient and reduces PCB and component temperatures.ApplicationsCommunication and Networking EquipmentFPGAsHigh-Current Voltage RegulatorsMemoryMicroprocessor ChipsetsNetworking ASICsServers and Storage Equipment |

MAX20796Dual-Phase Scalable Integrated Voltage Regulator with PMBus Interface | Voltage Regulators - Linear + Switching | 5 | Active | The MAX20796 offers a fully integrated, highly efficient, two-phase switching regulator for applications operating from 4.5V to 16V and requiring up to 60A maximum load or 90A with an optional third-phase external power stage. The output voltage range can be configured from 0.5V to 5.5V with some restrictions on duty cycle. The switching regulator uses a fixed-frequency control scheme providing an extremely compact, fast, and accurate power delivery solution for server and telecom applications. Integrated linear regulators allow single-supply operation. To further improve system efficiency and thermal performance, an external 3.3V supply or FET can be used to generate the core supply.Key system parameters are configured by external resistors, including the selection of soft-start timing, output voltage, switching frequency, PMBus™ address, overcurrent trip point, and loop control parameters. The device operates with either coupled or discrete inductors. Coupled inductor technology offers high performance with a minimum number of input and output capacitors for best-in-class solution cost.The MAX20796 includes fault protection and reporting capabilities. Inherent positive and negative overcurrent and overtemperature protection ensure a rugged design. Input undervoltage lockout shuts down the device when the input voltage is out of specification. Regulation is halted if the output voltage is outside of a programmable range. A PGOOD pin provides an output signal to show that the output voltage is within range and the system is regulating.The MAX20796 is offered in a 35-pin, 4mm × 10.5mm FC2QFN package, ideal for use in networking and communication end equipment.The device is also available as MAX20796A, which is preconfigured for a 1V, 800kHz application with LEAD_LAG enabled.ApplicationsCommunication, Networking, Servers and Storage EquipmentI/O and Auxiliary PowerMemory VDDQMicroprocessor ChipsetsPoint-of-Load Voltage Regulators |
