LM2731YMF/NOPB TI Step-Up DC-DC Converter | SOT-23-5 | 1.6MHz, 1.5A

Product Overview

The LM2731YMF/NOPB from Texas Instruments is a high-frequency, current-mode, step-up (boost) DC-DC converter in a compact SOT-23-5 package. It operates at a fixed switching frequency of 1.6 MHz, allowing the use of small external components. The device integrates a 1.5A, 40V power switch, making it suitable for applications requiring high output voltage from a low input voltage source. The LM2731YMF/NOPB features internal compensation, soft-start, and thermal shutdown, ensuring reliable operation in demanding environments.
