COSEL Surface Mount DC-DC Converters
Compact Power Conversion for Board-Level Integration
Surface Mount DC-DC Converters for Space-Constrained Designs
COSEL's surface mount DC-DC converters are developed for applications where board space is limited and reliable isolated power conversion is essential. With a wide range of power classes and input voltage options, they integrate directly onto the PCB - simplifying the power architecture and reducing wiring complexity.
The portfolio covers both isolated and non-isolated topologies, from low-power point-of-load (POL) converters to higher-power brick-format modules, addressing a broad spectrum of system requirements.
Designed for Demanding Applications
COSEL surface mount DC-DC converters are suited for use in:
- Industrial automation and embedded control systems
- Medical devices and patient-critical equipment
- Telecommunications and networking infrastructure
- Test and measurement systems
- Portable and battery-powered electronics

From Point-of-Load to Brick Format
The portfolio spans several converter families to match different design requirements. Non-isolated POL converters such as the BRDS Series handle low-voltage, fast-transient loads close to the point of consumption - ideal for FPGAs, ASICs, and digital logic. Isolated compact converters like the SUCS, SUS, and SUW Series provide galvanic separation across a wide input range in minimal footprint. Higher-power brick-format converters in the CHS Series scale up to several hundred watts, supporting demanding industrial and telecom loads with high efficiency and PMBus control.
Safety and Quality Standards
COSEL surface mount DC-DC converters comply with internationally recognised safety standards. EN and UL approvals are standard across the main product families, providing a reliable foundation for system certification. Selected series are designed in accordance with IEC 60601-1 requirements, making them suitable for use in medical device development.
