The Texas Instruments LMS3655NQRNLRQ1 is a high-performance synchronous step-down (buck) converter optimized for demanding applications. It provides a fixed 3.3V output voltage or an adjustable output from 1V to 20V, with a maximum continuous output current of 5.5A.
This AEC-Q100 qualified device operates with an input voltage range up to 36V, featuring transient tolerance up to 42V for robust surge protection. It boasts a peak efficiency of 96% when converting 12V to 5V and maintains high efficiency across various load conditions due to its automatic light load mode and seamless PWM/PFM mode transition. The fixed switching frequency is 400kHz (±10%), with options for external synchronization and pin-selectable forced PWM mode.
Key features include internal compensation, soft-start, current limiting, thermal shutdown, and undervoltage lockout (UVLO). It also provides a RESET output with an integrated filter and a 3ms release timer, simplifying system monitoring without additional components. The device is supplied in a 22-VQFN-HR (5x4 mm) package with wettable flanks for improved solder joint inspection.
Applications include automotive USB charging, driver monitoring systems, surround-view ECUs, and vehicle-to-vehicle communication.
