The Texas Instruments LMS3635AQRNLRQ1 is a high-performance synchronous step-down (buck) converter designed for automotive applications. It provides an output current of up to 3.5A and supports an adjustable output voltage from 1V to 20V.
Key electrical specifications include a fixed switching frequency of 400kHz, a peak efficiency of 96% when converting 12V to 5V, and a low quiescent current of 18µA. The device operates within an ambient temperature range of -40°C to +125°C and has a junction temperature range of -40°C to +150°C.
This converter is housed in a 22-VQFN-HR (5x4) package with wettable flanks, suitable for surface mounting. It features integrated compensation, soft-start, current limit, thermal shutdown, and UVLO protection. The device is AEC-Q100 qualified for automotive applications, making it suitable for use in automotive USB charging, driver monitoring, and surround-view systems.
Additional features include low EMI and minimized switch node ringing, an external frequency synchronization capability, and a RESET output with internal filter and 3ms release timer. An automatic light-load mode is included to improve efficiency.
