Digital Power Modules
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.

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.
