Quality Control: Learn More
The Microchip Technology LM2576-12BU is a monolithic integrated circuit providing all functions of a 3A constant-On-Time buck (step-down) voltage regulator. This device offers superior performance for switching power supplies, featuring a precisely regulated 12V output voltage and a maximum input voltage of 40V, with a minimum input of 4V. The LM2576-12BU operates at a switching frequency of 52kHz and utilizes a non-synchronous buck topology, delivering up to 3A of output current. Housed in a TO-263-5, D2PAK package, this surface-mount component is suitable for demanding applications across industrial automation, consumer electronics, and telecommunications sectors. The fixed output configuration simplifies design, and the wide operating temperature range of -40°C to 125°C (TJ) ensures reliable operation in challenging environments.
