Texas Instruments  LMS3655NQEVM

The LMS3655NQEVM evaluation module (EVM) demonstrates the capabilities of the LMS3655-Q1 automotive integrated buck converter. For optimized EMI performance, the LMS3655-Q1 has Spread Spectrum built in and the  EVM has an EMI filter on the back side that assists with noise reduction. The user can choose to bypass that EMI filter using  VIN1/GND1 posts. The EVM operates from a 3.8V to 36V input (up to 42V transients) and provides a fixed 3.3V output at 5.5A continuous load.
