LM2841YQMK/NOPB TI DC-DC Converter | TSOT-23-6 | 1.2A, 42V

Product Overview

The LM2841YQMK/NOPB from Texas Instruments is a high-voltage, 1.2A step-down (buck) DC-DC converter in a compact TSOT-23-6 package. It integrates a 42V power MOSFET and operates over a wide input voltage range of 4.5V to 42V, making it ideal for industrial, automotive, and telecom applications. The device features a fixed 550kHz switching frequency, internal compensation, and a low shutdown current of 2.5µA. With built-in protection features including cycle-by-cycle current limit, thermal shutdown, and undervoltage lockout, the LM2841YQMK/NOPB delivers reliable power conversion in space-constrained designs.
