Converters feature increased EMI and thermal performance
TI’s DC/DC buck regulators simplify the process of achieving EMI compliance and high reliability for rugged industrial and automotive applications.
Two families of wide-VIN synchronous DC/DC buck regulators with electromagnetic interference (EMI) and thermal performance have been introduced by Texas Instruments (TI).
The highly integrated 5A and 6A LM73605/6 and 2.5A and 3.5A LM76002/3 step-down voltage converters feature an optimized pinout and best-in-class thermal coefficient to simplify the process of achieving EMI compliance and higher reliability for rugged industrial and automotive power supplies.
The 3.5V to 36V LM73605/6 and 3.5V to 60V LM76002/3 buck regulators meet and exceed the demanding CISPR 25 Class 5 automotive electromagnetic compatibility (EMC) requirements. These regulators’ programmable output switching frequency can be set either above the AM band, which eliminates AM-band interference and reduces output filter size and cost, or below the AM band to optimize efficiency.
The small QFN package with wettable flanks delivers an ultra-low thermal coefficient to improve reliability and enables post-solder optical inspection to simplify manufacturing. Optimized package pin placement allows flexibility in board design to improve heat sinking, which minimizes radiated and conducted emissions.
