The LM2577SX-ADJ/NOPB from Texas Instruments is a monolithic integrated circuit designed for DC-DC power conversion. This device functions as a step-up or step-up/step-down regulator, offering flexibility in power supply design.
Key electrical characteristics include a wide input voltage range from 3.5V to 40V and a switch current limit of 3A. It operates at a frequency of 52kHz and supports adjustable output voltages. The regulator is non-synchronous and can be configured for positive or negative output.
This component is housed in a TO-263-6, D²Pak package and is designed for surface mounting. The operating temperature range is -40°C to 125°C (TJ), making it suitable for various environmental conditions. Its design incorporates features like current-mode operation for improved transient response and line regulation, along with a soft-start function to reduce in-rush current.
The LM2577SX-ADJ/NOPB is protected by current limit, under-voltage lockout, and thermal shutdown, enhancing its reliability in demanding applications.
