Overview
Description
The RAA210870 is a pin-strap configurable 70A step-down PMBus-compliant DC/DC power supply module that integrates a digital PWM controller, synchronous MOSFETs, power inductor, and passive components. Only input and output capacitors are needed to finish the design. Because of its thermally enhanced HDA packaging technology, the module can deliver up to 70A of continuous output current without the need for airflow or additional heat sinking. The RAA210870 simplifies configuration and control of Renesas digital power technology while offering an upgrade path to full PMBus configuration through the pin-compatible ISL8273M. Operating over an input voltage range of 4. 5V to 14V, the RAA210870 offers adjustable output voltages down to 0. 6V and achieves up to 93% conversion efficiencies. A unique ChargeMode™ control architecture provides a single clock cycle response to an output load step and can support switching frequencies up to 1MHz. The power module integrates all power and most passive components and requires only a few external components to operate. A set of external resistors allows the user to easily configure the device for standard operation. A standard PMBus interface addresses fault management, as well as real-time full telemetry and point-of-load monitoring. A fully customizable voltage, current, and temperature protection scheme ensures safe operation for the RAA210870 under abnormal operating conditions. The device is also supported by the PowerNavigator™ software, a full digital power train development environment. The RAA210870 is available in a low profile compact 18mm x 23mm x 7. 5mm fully encapsulated thermally enhanced HDA package.
