Renesas' digital PMBus power modules integrate a PWM controller, inductor, power MOSFETs, and passive components into one small package making the design of high efficiency, compact and intelligent power supplies easy.
What are Digital Power Modules
Digital power module ICs provide the benefits of both digital power and power modules, and support the growing industry trend toward high-efficiency power conversion because of their flexibility, high integration and high reliability.
Renesas module solutions include highly integrated POL DC/DC digital power modules in an innovative QFN style package. Renesas' digital modules integrate most of the components required to build a DC/DC power supply into a single device.
Digital Power Module Features
- Drag and drop system
- Click and drag sequencing
- Command tool library
- Pre-loaded common configuration for power FPGAs
- PMBus monitoring and configurability: works with other PMBus devices with common protocol
- Built-in auto-compensation provides optimal dynamic performance to minimize output voltage during transient events
- Adjustable voltage via PMBus command
- Simplified voltage tracking via PMBus
Ease of Design
- Renesas is committed to making it easy to design with Renesas parts. We offer OrCad schematic files, demo boards with common configurations already designed and tested.
Using Eagle CAD software? While Renesas provides OrCad schematic files for most parts, there are also many Eagle CAD libraries available for Renesas parts. Note: Renesas has not tested nor verified these Eagle CAD libraries; use at your own risk.

Industry-Leading 10A and 15A Fully Encapsulated PMBus Power Modules
The ISL828xM hybrid digital and ISL821xM analog power modules feature integrated LDOs that enable single-supply operation. They leverage Renesas’ patented R4™ high-speed control loop architecture with inherent line voltage feed-forward, providing designers a unique combination of ultra-fast load transient response and high noise immunity. Their proprietary Grid HDA package offers unmatched electrical and thermal performance 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 – even under heavy load conditions.
