Direct access to applications engineers in New Hampshire, USA, helping global procurement teams specify, sample, and qualify power components efficiently.
A DC-DC converter converts one DC input voltage into a regulated or unregulated DC output voltage at a different level. This includes step-down conversion (buck converter), step-up conversion (boost converter), or isolated ratio conversion to isolate electronic systems from input noise and ground loops.
Key categories include Isolated DC/DC Converters ( galvanic safety isolation up to 8kVDC), Non-Isolated Point-of-Load Regulators (high efficiency board-level step-down), High-Voltage Input DC/DC Converters (supporting 110V to 310V DC input buses), and Wide Input (4:1 / 10:1) Transportation Converters.
Medical DC/DC converters provide safety isolation (2×MOPP) between patient-connected circuits and primary internal supply voltages, ensuring minimal leakage current and meeting stringent safety standards under IEC 60601-1 third edition.
Select isolated converters when safety separation, ground isolation, noise immunity, or negative rail generation is required. Select non-isolated switching regulators when input and output share a common ground reference, and maximum energy efficiency, high power density, and lowest unit cost are critical.
Yes. When standard catalog products do not match your exact footprint, pinout, voltage requirements, or thermal operating range, our design team can adapt a modified standard or engineer a fully custom unit tailored to your specification.
