18mm DATASHEET RAA210850 FN9346 Rev.1.00 Pin-Configurable 50A DC/DC Power Module with PMBus Interface Mar 15, 2019 The RAA210850 is a pin-strap configurable 50A Features step-down PMBus-compliant DC/DC power supply Wide input voltage range: 4.5V to 14V module that integrates a digital PWM controller, Up to 96% efficiency synchronous MOSFETs, power inductor, and passive components. Only input and output capacitors are needed Programmable output voltage to finish the design. Because of its thermally enhanced 0.6V to 5V output voltage settings HDA packaging technology, the module can deliver up to 50A of continuous output current without the need for 1.2% V accuracy over line, load, and OUT airflow or additional heat sinking. The RAA210850 temperature simplifies configuration and control of Renesas digital PMBus compliant communication interface power technology while offering an upgrade path to full Pin-strap mode for standard settings PMBus configuration through the pin-compatible ISL8272M. V , switching frequency, input UVLO, OUT soft-start/stop, and external synchronization The RAA210850 operates with the ChargeMode control architecture, which responds to a transient load Real-time telemetry for V , V , I , IN OUT OUT within a single switching cycle. The RAA210850 can be temperature, duty cycle, and switching frequency easily programmed with pin-strap resistors to set the Complete overvoltage, undervoltage, current and output voltage, switching frequency, input UVLO, temperature protections with fault logging soft-start/stop, and device addresses. PMBus can be used to monitor voltages, currents, temperatures, and fault PowerNavigator supported status. The RAA210850 is supported by Thermally enhanced HDA package PowerNavigator software, a Graphical User Interface Applications (GUI), that can configure modules for desired solutions. Server, telecom, storage, and datacom The RAA210850 is available in a low profile, compact, (18mmx23mmx7.5mm) fully encapsulated, thermally Industrial/ATE and networking equipment enhanced HDA package, suitable for automated General purpose power for ASIC, FPGA, DSP, and assembly by standard surface mount equipment. memory Related Literature For a full list of related documents, visit our website: RAA210850 product page VIN VIN VOUT CIN VOUT VDD VSENP ENABLE COUT EN VSENN VR5 10F 10F VR6 VR VR55 RAA210850 VDRV VCC SCL VDRV1 100k PMBus SDA 2x10F Interface SALRT VMON 7.5mm 6.65k SGND PGND Note: 1.
