The LM2576S-12/NOPB from Texas Instruments is a monolithic integrated circuit designed for step-down (buck) switching regulator applications. It is capable of driving a 3A load with excellent line and load regulation, offering a fixed 12V output voltage.
This regulator operates at a fixed frequency of 52kHz and requires minimal external components, simplifying design. It features TTL-shutdown capability for low-power standby modes and provides fault protection. The device is suitable for applications requiring an efficient replacement for linear regulators, substantially reducing the need for large heat sinks.
Packaged in a TO-263-6, D²Pak (5 Leads + Tab), TO-263BA surface-mount package, the LM2576S-12/NOPB operates within an ambient temperature range of -40°C to 125°C (TJ). Its positive output configuration and step-down topology make it versatile for various power management needs.
