LMS3655MMRNLR Description

Short technical summary and product information.

The Texas Instruments LMS3655MMRNLR is a high-performance synchronous step-down DC-DC converter designed for efficient power management. It supports an input voltage range from 3.5V to 42V and can deliver an output current of up to 5.5A. The output voltage is adjustable from 0.8V to 15V, providing flexibility for various applications.

 

This converter operates at a nominal switching frequency of 400kHz (±10%), contributing to its compact solution size and high efficiency, achieving up to 96% peak efficiency when converting 12V to 5V. Key features include synchronous rectification for improved efficiency, automatic light load mode, and pin-selectable forced PWM mode. The device operates within an ambient temperature range of -40°C to 125°C.

 

The LMS3655MMRNLR is housed in a 22-VQFN-HR (5x4 mm) package with wettable flanks, suitable for surface mounting. Its design incorporates built-in compensation, soft start, current limit, thermal shutdown, and UVLO protection, simplifying system design and enhancing reliability.
