5 Summary

Texas Instruments' Enhanced HotRod QFN package technology leverages the low noise performance of the FCOL package and the thermal benefits of a standard QFN package with a thermal DAP. The LM60440, LM60430, LM60440-Q1, and LM60430-Q1 are TI's first DC/DC converters with the Enhanced HotRod QFN package. As illustrated throughout the application note, the LM60440 product family achieves best in class EMI performance and passes the most stringent CISPR 25 Class 5 limits. In addition the thermal pad of the LM60440 and LM60440-Q1 enables 4-A output current capability in ultra-small 3-mm × 2-mm Enhanced HotRod QFN package. Ultimately, the Enhanced HotRod QFN package leverages the low-noise enhancements of FCOL technology and the thermal enhancements of a standard QFN package to enable best-in-class low EMI in industry's smallest 4-A converter, the LM60440.
