MAX20796GFB+

MAX20796GFB+ is a dual phase scalable integrated voltage regulator with PMBus interface. It offers 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. Application includes point-of-load voltage regulators, communication, networking, servers, and storage, equipment, microprocessor chipsets, memory VDDQ, I/O and auxiliary power.
