Analog Devices / Maxim Integrated MAX20743 Step-Down Switching Regulator

Analog Devices MAX20743 Step-Down Switching Regulators are fully integrated, highly efficient switching regulators with PMBus™ for applications operating from 4.5V to 16V and requiring up to 35A maximum load. This single-chip regulator provides extremely compact, high-efficiency power delivery solutions with high-precision output voltages and excellent transient response for networking, datacom, and telecom equipment. The MAX20743 regulator offers a broad range of programmable features through either the PMBus or a capacitor and resistor connected to a dedicated programming pin.

This feature can optimize the operation for a specific application, reducing the component count and/or setting appropriate trade-offs between the regulator’s performance and system cost. The Analog Devices MAX20743 step-down switching regulator offers the ease of programming that enables using the same design for multiple applications.
