Board mount power supplies are compact, PCB integrated power conversion modules that deliver regulated, conditioned output power directly on a circuit board. Choosing a board mount supply maximizes PCB real estate, minimizes external cabling, and enhances thermal coupling. These modules are widely used in embedded systems, industrial controls, communications, medical instrumentation, and distributed power architectures.

Types of Board Mount Power Supplies

• AC DC Converters - Transforming mains voltage (120-240 VAC) into regulated DC (5-48 VDC), often with isolation for safety and EMI filtering for compliance.
• DC DC Converters - Step raw DC (12V, 24V) to isolated or non-isolated outputs with high-density switching, tight regulation, and high efficiencies.
• LED Drivers - Constant-current modules optimized for LED lighting systems, with dimming and thermal protections.

Key Advantages and Regulatory Compliance

Board mount power supplies provide an engineer significant advantages and market approved regulatory compliances out of the box compared to custom built power solutions.

• High efficiency - often greater than 90%, reducing heat dissipation and lowering external cooling requirements.
• Compact industry-standard footprints (full brick, quarter-brick, eighth-brick), enabling modular power system design.
• UL/IEC 60950-1, IEC 62368-1, and EN 60601-1 safety standards ensure safe isolation levels, creepage/clearance distances, and protection against shock and fire hazards.
• EMI/EMC Compliance (EN55032, FCC Part 15, CISPR) prevents conducted and radiated emissions from disrupting nearby circuits and ensures the supply isn’t vulnerable to external interference.
• Market Access - CE marking in Europe, UL recognition in North America, and CCC in China are often required for product deployment, saving costly safety requalifications later in the design cycle.
