MAX20796

Dual-Phase Scalable Integrated Voltage Regulator with PMBus Interface

Smallest, High Efficiency, 60A Fully Integrated Two-Phase Switching Voltage Regulator


点击查看特定型号的库存状况。

说明

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, 4 × 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.
