LM2731YMF TI Switching Regulator | SOT-23-5 | 1.6MHz, 1.5A

Product Overview

The LM2731YMF from Texas Instruments is a high-frequency, current-mode boost converter in a compact SOT-23-5 package. It operates at a fixed 1.6MHz switching frequency, allowing for small external components. The device integrates a 1.5A, 40V power switch, making it suitable for generating high voltages from low-voltage inputs. With an input voltage range of 2.7V to 14V, it can be powered from single-cell Li-Ion batteries or regulated 5V/12V rails. The LM2731YMF features internal compensation, soft-start, and thermal shutdown, simplifying design and enhancing reliability.
