Renesas' family of analog power modules offers users a fully integrated DC/DC switching buck converter in one package. These modules combine the controller, power FETs, output inductor, and compensation circuitry in a single package minimizing both the external component count and complexity of converter design.

What are Analog Power Modules

Analog power modules combine controllers, power FETs, output inductors and compensation circuitry in a single package to minimize both the external component count and complexity of converter design.

To meet the challenge of designing the power sub-system for infrastructure systems, many designers are considering using power modules instead of traditional discrete POL designs, with time to market, size constraints, reliability and design capabilities being motivating factors.

Renesas offers a comprehensive portfolio of digital and analog point-of-load power modules to address the needs of infrastructure systems. Renesas power modules are complete DC/DC power sub-systems. With industry-leading power technology, these modules reduce design time, lower cost and save board space. Renesas’ optimized thermal packaging technology provides excellent thermal performance, providing high current operation and high power density without the need for an external heat sink or fan, reducing system cost.

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.
