Overview

Description

The RAA210130 is a fully PMBus enabled DC/DC step-down power supply capable of delivering up to 30A of current from a compact 10mm × 13mm × 7.8mm thermally enhanced BGA package.

Operating across an input voltage range of 4.75V to15V, the RAA210130 offers adjustable output voltages down to 0.45V and achieves up to 96% efficiency. The RAA210130 implements the proprietary Renesas digital synthetic current modulation scheme to achieve an industry-leading combination of transient response, ease of tuning, and efficiency across the full load range. With minimal external components, simple configuration, robust fault management, and highly accurate regulation capability, implementing a high-performance regulator has never been easier.

A standard PMBus interface with PMBus V1.3 compatibility facilitates device configuration, addresses sequencing and fault management, provides real-time full telemetry and point-of-load monitoring, and detailed fault reporting. All of these features are conveniently accessible through the PowerNavigator™ software tool.

A fully customizable cycle-by-cycle current (peak overcurrent and peak undercurrent limit), voltage, and temperature protection scheme is capable of latching off or restarting the output in response to system faults.
