New ICs enable efficient, flexible DC/DC designs with reduced footprint and high-frequency performance
To expand design flexibility in power electronics, RECOM Power has introduced a new range of discrete rectifier ICs to support engineers building custom isolated DC/DC power supplies. The portfolio combines integration, efficiency, and high-frequency capability to address the growing demand for compact, optimised power architectures across industrial and embedded systems.
At the core of the launch is a fully integrated full-bridge rectifier designed to reduce board space while improving efficiency. By integrating MOSFETs and Schottky diodes into a compact package, the device eliminates the need for multiple discrete components typically required in conventional rectification stages. This approach not only simplifies layouts but also reduces conduction losses.
The key features are:
- Integrated full-bridge rectifier with MOSFETs and Schottky diodes
- Intelligent output voltage limiting for no-load protection
- High-frequency operation up to 700 kHz
- Ultra-fast switching: 30 ns turn-on, 10 ns turn-off
- Wide temperature range: −40°C to +125°C
A key differentiator is the inclusion of an intelligent output voltage limiter. This feature prevents excessive voltage rise under no-load conditions, enhancing system reliability. Importantly, the limiter remains inactive during load operation, ensuring it does not compromise efficiency—an essential factor in modern high-performance power designs.
Complementing this is a synchronous rectification controller tailored for high-frequency applications. Operating up to 700 kHz, it delivers ultra-fast switching performance, enabling improved efficiency in compact power supplies. The controller is self-powered from an AC input, allowing flexible deployment in both high-side and low-side configurations. It also supports multiple operating modes and flyback topologies, making it adaptable to a wide range of designs.
Both solutions are engineered for robustness, with wide operating temperature support and compatibility with standard reflow soldering processes. This makes them suitable for demanding environments such as industrial automation, telecom infrastructure, and advanced consumer electronics.
The introduction signals a shift toward giving designers greater control over power architectures—bridging the gap between fully integrated modules and discrete implementations. By combining integration with flexibility, these rectifier ICs enable optimised performance without the traditional trade-offs in space, efficiency, or design complexity.
