    Frequently Asked Questions

    SIP switching regulators are engineered for specialists requiring efficient, non-isolated voltage conversion in space-constrained through-hole designs. Primarily deployed in industrial controls, embedded systems, and battery-powered electronics, they are essential where minimizing thermal output and maximizing system efficiency are paramount. Their single-in-line format ensures seamless integration into both dense legacy and modern PCB layouts.
    The primary advantage is efficiency. While linear regulators dissipate excess voltage as heat—often requiring large, expensive heatsinks—switching regulators convert the voltage with up to 97% efficiency. This drastically reduces thermal output, eliminates the need for heatsinks, and extends the life of surrounding components.
    No, SIP switching regulators are non-isolated (the input and output share a common ground). They are intended for point-of-load (POL) conversion where galvanic isolation is not required. If your application requires protection from high-voltage transients or a separate ground, you should consider RECOM’s isolated DC/DC converters.
    Yes, many SIP buck regulators are specifically engineered as pin-compatible upgrades for standard 78xx linear regulators. This allows specialists to enhance efficiency and modernize existing systems with minimal redesign overhead, leveraging drop-in compatible formats to accelerate development cycles.
