Industry-Leading Integrated Package
Designed for maximum ease-of-use, the patent-pending packaging technology includes a single exposed copper bottom pad with standard IC leads for superior layout and thermal performance. The single exposed bottom makes prototyping easy in applications labs, while the convenient size and lead pitch allow for the same pick-and-place manufacturing as the standard TO-263 package.

Low EMI
Ideal for noise-sensitive applications, the SIMPLE SWITCHER power modules feature an optimized internal layout with an integrated shielded inductor and an input filtering capacitor to reduce noise and EMI. The pin-out of the power module allows input and output capacitors to be placed as close as physically possible to the package, reducing the area of the high di/dt current paths.

Excellent thermal performance with no airflow requirement, combined with low operating temperature and low system heat generation, make the SIMPLE SWITCHER power modules a reliable and robust solution. Plus, the single exposed bottom coupled with efficient heat dissipation technology eliminates the need for external heat sinks or fans while guaranteeing operation at ambient temperatures from -40˚C to 85˚C (extended -55˚ C ambient temperature versions also available) reducing design complexity and cost.

SIMPLE SWITCHER EXT power modules provide excellent performance in the most extreme conditions, with extended ambient temperatures guaranteed down to -55˚ C and shock and vibration testing that meets military and industrial standards.
