MAX20730

Integrated, Step-Down Switching

Regulator with PMBus

General Description

The MAX20730 is a fully integrated, highly efficient switch-

ing 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 IC 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.

The IC includes protection and telemetry features. Positive

and negative cycle-by-cycle overcurrent protection and

overtemperature protection ensure a rugged design.

Input undervoltage lockout shuts down the device to

prevent operation when the input voltage is out of

specification. A status pin provides an output signal to

show that the output voltage is within range and the

system is regulating.
