The Texas Instruments LM2577T-ADJ is a monolithic integrated circuit designed for power management applications. It functions as a step-up, step-up/step-down, boost, flyback, or forward converter.
Key electrical specifications include a wide input voltage range from 3.5V to 40V and a switch current limit of 3A. The device operates at a frequency of 52kHz and features an adjustable output configuration. It is designed with nonsynchronous rectification and includes protection features like current limit, under-voltage lockout, and thermal shutdown.
This regulator is housed in a TO-220-5 package and is designed for through-hole mounting. The operating temperature range is -40°C to 125°C (TJ). Its low component count and integrated features simplify power supply designs, making it suitable for various applications requiring efficient voltage conversion.
