Analog Devices / Maxim Integrated MAX20730 Step-Down Switching Regulator

Analog Devices MAX20730 Step-Down Switching Regulator is a fully integrated, highly efficient switching regulator with PMBus™ for applications operating from 4.5V to 16V and requiring up to 25A (max) 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 Analog Devices MAX20730 offers a broad range of programmable features through either the PMBus or a capacitor and resistor connected to a dedicated programming pin. Using this feature, the operation can be optimized for a specific application, reducing the component count and/or setting appropriate trade-offs between the regulator’s performance and system cost. Ease of programming enables using the same design for multiple applications.
