RAA2109252GLG#AG0

The RAA210925 is a pin-strap configurable dual 25A 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 25A of continuous output current without the need for airflow or additional heat sinking. The RAA210925 simplifies configuration and control of Renesas digital power technology while offering an upgrade to full PMBus configuration through the pin-compatible ISL8274M. Operating across an input voltage range of 4. 5V to 14V, the RAA210925 offers adjustable output voltages down to 0. 6V and achieves up to 95. 5% 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 1067kHz. The power module integrates all power and most passive components and requires only a few external components to operate. The RAA210925 comes with a preprogrammed configuration for operating in Pin-strap mode. Output voltage, switching frequency, input UVLO, soft-start/stop delay and ramp times, tracking function, and the device SMBus address can be programmed with external pin-strap resistors. A standard PMBus interface addresses fault management, as well as real-time full telemetry and point-of-load monitoring. The RAA210925 is supported by PowerNavigator™ software, a Graphical User Interface (GUI), that can configure modules for desired solutions. The RAA210925 is available in a low profile, compact 18mm x 23mmx 7. 5mm fully encapsulated, thermally enhanced HDA package.
