DC/DC Converters

DC/DC Voltage Converters: From 0.25W to 1000W for Every Design Requirement

Adapting, stabilizing, and galvanically isolating direct current rails are critical requirements in the development of electronic circuit boards, embedded systems, and complex industrial equipment. Power-Supply.it provides an extensive, diversified range of DC/DC voltage converters, with rated outputs spanning from 0.25W to over 1000W, tailored to serve precision low-power circuits as well as demanding high-power stages.

Our catalog allows you to select DC/DC converters engineered for any circuit topology:

• Regulated and Unregulated Converters: High-density, cost-effective unregulated modules for stable load demands, or closed-loop regulated DC/DC converters designed to maintain a strictly constant output voltage regardless of line fluctuations or dynamic load transitions.
• Input Voltage Ranges: Fixed-input configurations (±10%), wide 2:1 and 4:1 input options, up to ultra-wide 10:1 range architectures ideal for railway, vehicle-mounted, and telecommunications installations exposed to heavy voltage sags or high transient spikes.
• Standard Industrial Packages: Broad mechanical interchangeability across miniaturized PCB through-hole form factors (SIP and DIP), surface-mount SMD modules for pick-and-place lines, and ruggedized Brick converters (Full, Half, Quarter, and 1/16 Brick) encapsulated in plastic or metal cases for effective conduction cooling via baseplate, chassis, or heatsink.

Comprehensive Range and MEAN WELL Catalog

Through our close collaboration and official distribution channel for the MEAN WELL portfolio, we deliver a complete lineup of DC/DC converters certified according to leading global safety standards (CE, UL, IEC/EN 62368-1, and EN 50155 for railway compliance). Mean Well manufacturing standards guarantee high energy efficiency (up to over 92%), high I/O isolation (up to 6 kVDC), and high MTBF ratings, minimizing the risk of system downtime.

Pre- and Post-Sales Technical Consulting for Tailor-Made Solutions

Selecting the ideal converter requires evaluating operating thermal derating, acceptable output ripple and noise, and required isolation barriers between primary and secondary circuits. Our engineering team assists hardware developers, R&D departments, and system integrators with:

• Selection Guidance: Support in identifying the optimal footprint (SIP/DIP/SMD/Brick) and calculating thermal dissipation under real-world operating conditions.
• EMI Filtering and EMC Compliance: Reference schematics, external filter network designs aligned with EN 55032 limits, and input reverse-polarity protection circuits.
• Supply Chain Continuity: Readily available stock, rapid prototyping samples, and direct post-sales technical support for production batches and replacement parts.
