The five RAA210xxx simple digital power modules offer advanced digital telemetry and performance and are as easy to use as Renesas’ analogue power modules. They are complete step-down regulated power supplies that deliver 25A, 33A, dual 25A, 50A, and 70A of output current, while operating from industry-standard 12V or 5V input power rails.
The RAA210xxx family provides point-of-load (POL) conversion for advanced FPGAs, DSPs, ASICs and memory used in servers, storage, optical networking, and telecom equipment. Each device integrates a PWM controller, MOSFETs, inductor and passives inside a thermally optimised, High Density Array (HDA) encapsulated module. All that is needed to complete the power supply are input and output bulk capacitors.
The RAA210xxx is a lower cost, simplified digital power module family that is pin-to-pin compatible with Renesas’ full featured digital ISL827xM series. The RAA210xxx simple digital power modules offer run-time digital programmability to support configuration changes with a subset of PMBus commands, and full telemetry and system monitoring. If more advanced digital control is later required, upgrading to the pin-compatible ISL827xM modules will enable current sharing with multiple modules connected in parallel, access to all PMBus commands using the PowerNavigator tool, and non-volatile memory for configuration storage.
