It integrates the synchronous rectifier, so no external Schottky diode is needed, and the switching frequency runs up to 350 kHz — a practical balance between inductor size and switching loss for point-of-load conversion in industrial and telecom equipment. The 20-SSOP package keeps the footprint compact, and the -40°C to 85°C temperature grade covers outdoor and factory-floor environments. ## Package and thermal considerations The 20-SSOP (0.209\" body width, 5.30 mm wide) is a standard surface-mount footprint with a pitch that suits manual rework and automated assembly alike. No exposed pad is listed, so thermal dissipation relies on the copper area on the PCB — for 3 A continuous, plan on at least 1 square inch of 1 oz copper on the top layer under the part, with vias to a ground plane. The synchronous rectifier helps efficiency, but at full load the package will warm up; staying within the -40°C to 85°C ambient range is straightforward with reasonable airflow. ## Lifecycle and compliance The MAX1623EAP+ carries an Active lifecycle status and is ROHS3 compliant, so there is no end-of-life pressure on this BOM line. No replacement or second-source part is listed in the official record, but the part is current-production and available through independent distribution. The ROHS3 compliance means it meets the latest EU restriction levels, including exemptions for lead in high-temperature solders.","metaTitle":"Maxim MAX1623EAP+ Buck Regulator, 3A, 20-SSOP","metaDescription":"Maxim MAX1623EAP+ step-down buck regulator, 3A output, up to 350kHz switching, adjustable output 1.1V-3.8V, -40°C to 85°C, 20-SSOP.
