The synchronous rectifier (internal low-side FET) keeps efficiency above 90% across most of the load range, which matters when the 4 A output is running near full current and the board has limited airflow. The part is ROHS3 compliant, and the tube packaging is standard for prototype and low-to-medium volume builds; for reel quantities, check the alternate order code suffix.","metaTitle":"LM20154MH/NOPB Texas Instruments Buck Regulator, 4 A, 1 MHz","metaDescription":"TI LM20154MH/NOPB step-down buck regulator, 4 A output, 1 MHz switching, adjustable 0.8-4.68 V, 16-HTSSOP.
