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 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 optimized, 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.
“Our simple digital power modules accelerate time to market for design teams that want an easier-to-use, lower-cost digital power solution,” said Philip Chesley, Vice President of Industrial Analog and Power Business Division at Renesas. “The RAA210xxx simple digital power products continue Renesas’ leadership in power density, high efficiency and fast transient performance to support demanding multi-rail POL requirements.”
The proprietary HDA package offers higher electrical and thermal performance at full load through a single-layer conductive package substrate that efficiently transfers heat from the module to the system board, and dissipates it without requiring airflow or heatsinks. Space-constrained boards take full advantage of the HDA’s high power density, which Renesas says is not achievable with discrete components.

This uses Renesas’ patented ChargeMode control architecture that delivers up to 96 percent peak efficiency and better than 90 percent efficiency under most conditions. They also provide single-clock-cycle fast transient response to output current load steps, which reduces capacitance and saves cost and board space.
Power supply designers can combine the RAA210xxx simple digital power modules with the 3A ISL8203M, 5A ISL8205M and 15A ISL8215M analogue power modules, and Renesas low-dropout regulators (LDOs) to support ancillary power rails in embedded applications.
The PowerCompass tool helps users quickly identify the right power modules and other parts that match their specific requirements. Multiple power rails can be set up for more than 200 FPGAs, and designers can perform high-level system analysis and generate custom reference design files in minutes. The PowerNavigatorTM tool allows designers to set up the simple digital power module’s sequencing, telemetry and real-time configuration.
The RAA210xxx simple digital power modules and evaluation boards are available now from Renesas Electronics’ worldwide distributors. Module prices range from $18.38 USD for the 25-amp RAA210825, up to $51.75 USD for the 70-amp RAA210870 in 1k quantities.
