The LM2576SX-5.0/NOPB from Texas Instruments is a monolithic integrated circuit designed as a step-down (buck) voltage regulator. It provides a fixed 5V output voltage with a maximum output current of 3A. This regulator operates at a fixed switching frequency of 52kHz, simplifying external component selection and reducing overall solution size.
The device requires minimal external components, typically only four, making it a low component count solution. It is designed for a wide input voltage range up to 40V. The LM2576 series features internal switch current limiting, thermal shutdown, and undervoltage lockout, providing robust protection.
Packaged in a TO-263-5 surface-mount package, the LM2576SX-5.0/NOPB is suitable for various power management applications. Its operating temperature range is -40°C to 125°C (TJ). The regulator is a non-synchronous type, meaning it uses a diode for rectification.
This regulator is ideal for applications requiring a simple and efficient step-down voltage conversion. Its fixed output voltage and current capability make it a reliable choice for power supplies and other DC/DC conversion needs.
