Renesas Electronics offers a range of DC/DC power modules that integrate controllers, power FETs, inductors, and passive components into compact, pre-tested packages. These modules are designed to simplify power supply design by reducing external component count and layout complexity while maintaining high efficiency. They typically operate over wide input voltage ranges—for example, from 4.5 V up to 80 V depending on the device—and provide regulated outputs suitable for powering digital ICs, processors, and system peripherals.
The modules support various current ratings, with options delivering from a few amperes to tens of amps of continuous output current. High-current modules use advanced packaging to enhance thermal performance and reduce power loss, enabling operation in dense or thermally constrained systems. Efficiency is maximized using synchronous buck architectures, optimized switching controllers, and integrated magnetics that reduce parasitics.
Renesas incorporates protection and control features such as overcurrent protection, thermal shutdown, undervoltage lockout, and soft-start sequencing. Many devices also provide power-good indicators, tracking functions, and programmable output voltages, giving engineers flexibility in system-level integration. With fixed-frequency operation and minimized EMI, these modules are suited for noise-sensitive applications, including industrial, communications, and automotive systems.
From a design perspective, Renesas DC/DC power modules allow engineers to focus on system-level design rather than detailed power stage optimization. Their combination of wide input ranges, integrated magnetics, high efficiency, and built-in protections make them suitable for applications where board space is limited and reliable power delivery is critical.
