DATASHEET RAA210870 FN9345 Rev.1.00 Pin-Configurable 70A DC/DC Power Module with PMBus Interface Oct 23, 2018 The RAA210870 is a pin-strap configurable 70A Features step-down PMBus-compliant DC/DC power supply 70A single channel output current module that integrates a digital PWM controller, 4.5V to 14V single rail input voltage synchronous MOSFETs, power inductor, and passive components. Only input and output capacitors are needed Up to 93% efficiency to finish the design. Because of its thermally enhanced Programmable output voltage HDA packaging technology, the module can deliver up to 70A of continuous output current without the need for 0.6V to 2.5V output voltage settings airflow or additional heat sinking. The RAA210870 1.2% accuracy over line, load, and temperature simplifies configuration and control of Renesas digital ChargeMode control loop architecture power technology while offering an upgrade path to full PMBus configuration through the pin-compatible 296kHz to 1.06MHz fixed switching frequency ISL8273M. operations Operating over an input voltage range of 4.5V to 14V, the No compensation required RAA210870 offers adjustable output voltages down to Fast single clock cycle transient response 0.6V and achieves up to 93% conversion efficiencies. A unique ChargeMode control architecture provides a PMBus interface and/or pin-strap mode single clock cycle response to an output load step and can Programmable through PMBus support switching frequencies up to 1MHz. The power Pin-strap mode for standard settings module integrates all power and most passive components and requires only a few external components Real-time telemetry for V , V , I , IN OUT OUT to operate. A set of external resistors allows the user to temperature, duty cycle, and f SW easily configure the device for standard operation. A Complete over/undervoltage, current, and standard PMBus interface addresses fault management, temperature protections with fault logging in addition to real-time full telemetry and point-of-load monitoring. PowerNavigator supported A fully customizable voltage, current, and temperature Thermally enhanced 18mmx23mmx7.5mm HDA protection scheme ensures safe operation for the package RAA210870 under abnormal operating conditions.
