RAA210870
RAA210870 is DC/DC Power Module manufactured by Renesas.
Pin-Configurable 70A DC/DC Power Module with PMBus Interface
FN9345 Rev.1.00 Oct 23, 2018
The RAA210870 is a pin-strap configurable 70A step-down PMBus-pliant DC/DC power supply module that integrates a digital PWM controller, synchronous MOSFETs, power inductor, and passive ponents. 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-patible 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 Charge Mode™ 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 ponents and requires only a few external ponents 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, in addition to 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 Power Navigator™ software, a full digital power train development environment.
The RAA210870 is available in a low profile pact 18mmx23mmx7.5mm fully encapsulated thermally enhanced HDA package.
