Many electronic systems operate using multiple voltage levels, even when the main power source provides only one DC voltage. Different parts of the system such as processors, memory, sensors, and communication circuits often need different voltage levels to operate correctly. Using linear regulation in these cases can cause high power loss and excessive heat generation, especially when the voltage difference is large. This reduces overall efficiency and can affect long-term system reliability. A DC-DC converter helps solve this by converting one DC voltage level to another efficiently.

Many deployed systems rely on DC-DC converters selected during initial power design. These converters are usually optimized for specific input voltage ranges, load profiles, and thermal operating limits. When a DC-DC converter reaches end-of-life, replacing it is not always simple. Differences in switching behavior, control method, efficiency, or pin layout can affect power stability and EMI performance.
This is common in industrial, automotive, and telecom systems where products may remain active for many years. Maintenance teams often need the same converter to avoid power redesign or recertification. Delays in sourcing compatible converters can increase downtime and maintenance cost.
Maketronics supports global engineering and procurement teams with reliable sourcing of both active and obsolete DC-DC Converters.
A DC-DC converter is an electronic device that efficiently converts one DC voltage level to another while maintaining stable output and minimizing energy loss.
They use switching techniques to transfer energy instead of dissipating excess voltage as heat, resulting in higher efficiency and lower thermal loss.
They are widely used in embedded systems, automotive electronics, telecom equipment, battery-powered devices, and computing hardware.
Replacing an obsolete converter may require power redesign and validation because differences in switching behavior, efficiency, and pin configuration can affect system stability and EMI performance.
