The Texas Instruments LMS3655MQRNLRQ1 is an automotive-grade synchronous step-down (buck) converter designed for efficient power management. It can deliver up to 5.5A of output current with an input voltage range of 3.5V to 42V and an adjustable output voltage from 1V to 15V.
This converter features a fixed switching frequency of 400kHz (±10%), contributing to a compact solution size and predictable performance. It boasts a high peak efficiency of 96% when converting 12V to 5V, and a low quiescent current of 15nA, making it suitable for applications requiring power efficiency.
The LMS3655MQRNLRQ1 operates over a wide junction temperature range of -40°C to +150°C, with an ambient operating temperature range of -40°C to +125°C. It is supplied in a 22-VQFN-HR (5x4 mm) package with wettable flanks for surface mounting, facilitating automated assembly and improved solder joint reliability.
Key features include over-current protection, power good signal, soft start, and spread spectrum for reduced EMI. The device is AEC-Q100 qualified for automotive applications.
