The LM2576-12BU from Micrel Inc. is an obsolete integrated circuit designed as a step-down (buck) switching regulator. It provides a fixed positive output voltage of 12V and can deliver up to 3A of output current. The device accepts an input voltage ranging from 4V to a maximum of 40V, making it suitable for a variety of power supply applications.
This regulator operates at a switching frequency of 52kHz. It is designed for surface mount applications and comes in a TO-263-6, D²Pak package. The operating temperature range is from -40°C to 125°C (TJ). As a non-synchronous rectifier, it simplifies circuit design for power management systems.
Key electrical characteristics include its wide input voltage range and substantial output current capability. The fixed output voltage simplifies design by eliminating the need for external feedback components for voltage setting. Its surface mount package is suitable for automated assembly processes.
