The LM2576-12WT from Microchip Technology is a monolithic integrated circuit designed as a step-down (buck) switching regulator. It provides a fixed 12V output voltage and can deliver up to 3A of load current.
This regulator is designed for simplicity, requiring minimal external components and featuring internal frequency compensation and a fixed-frequency oscillator operating at 52kHz. It offers an efficient replacement for linear regulators, often eliminating the need for a heat sink. The wide input voltage range of 4V to 40V makes it suitable for various applications.
Key electrical specifications include a guaranteed 3A output current and a fixed 12V output. The device includes protection features such as cycle-by-cycle current limiting and thermal shutdown for reliability under fault conditions. The operating temperature range is -40°C to 125°C (TJ).
The LM2576-12WT is packaged in a TO-220-5 configuration and is designed for through-hole mounting. Its robust design and integrated features simplify the development of switch-mode power supplies.
