COSEL & Powerbox Non-Isolated DC/DC Converters (POL)
Efficient Point-of-Load Power Conversion for Modern Board Designs
As digital systems become more complex, the demand for tightly regulated, low-voltage supply rails close to the load has grown significantly. Processors, FPGAs, ASICs, and memory devices all require precise core voltages that cannot be efficiently derived directly from a system bus. Point-of-load (POL) conversion - placing the voltage conversion as close as possible to the consuming device – is the established solution to this challenge.
FORTEC Switzerland offers non-isolated DC/DC converters from COSEL and Powerbox covering a range of input voltages, output power levels, and application profiles. From sub-watt point-of-load regulators for processor core supplies to multi-watt non-isolated converters suited to industrial and railway environments, the portfolio provides a well-matched solution for board-level power distribution requirements.
Designed for Industrial, Computing, and Infrastructure Applications
Non-isolated DC/DC converters from COSEL and Powerbox are well suited for use in a broad range of applications, including:
- Processor, FPGA, ASIC, and memory core voltage supply
- Industrial control and automation systems
- Railway and transportation electronics
- Telecommunications and network infrastructure
- Embedded computing and edge systems
- Test and measurement equipment
Technical Characteristics
The non-isolated portfolio covers a range of technical requirements relevant to modern board-level power design:
- Input voltage ranges from 3.3 V up to 154 V DC across the portfolio, accommodating a wide variety of system bus voltages
- Output voltages from 0.6 V for processor core supply through to 48 V for higher-voltage distribution rails
- Output power from low-power POL conversion up to 24 W for distributed supply applications
- Fast transient response on POL variants for stable supply under dynamic processor loads
- PMBus interface on the COSEL POL series for digital monitoring, sequencing, and control
- Built-in Remote On/Off and Power Good signalling for system-level power management
- Non-isolated topology on selected Powerbox variants specifically designed for applications where galvanic isolation is not required
- Railway-compliant variants available for transportation system integration
- SMD and through-hole mounting options across the Powerbox series
- Convection cooling with no moving parts for maintenance-free operation
- EN and UL safety approvals on COSEL series
- 5-year manufacturer warranty on COSEL products
- Long product lifecycles and consistent manufacturing quality from both manufacturers
A Complementary Portfolio for Diverse POL Requirements
The COSEL and Powerbox non-isolated converter range covers two distinct needs within board-level power design. The COSEL POL series targets the very low output voltage rails required by modern digital logic and processor cores, with PMBus control and fast transient response making it well suited to high-performance computing and communications designs. The Powerbox non-isolated series addresses a broader output voltage range with flexible mounting options and railway-compliant variants, making it applicable to both general industrial designs and transportation-certified platforms.
Together, they offer a complementary selection that covers the majority of non-isolated board-level conversion requirements without the need to source from multiple unrelated suppliers.
