The LM2576S-5.0 from UMW (Youtai Semiconductor) 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 5V output voltage.
This regulator requires a minimal number of external components, simplifying design. It features internal frequency compensation and a fixed-frequency oscillator operating at 52kHz. The device provides a high-efficiency replacement for linear regulators, often eliminating the need for a heat sink. Key electrical specifications include a guaranteed 3A output current and an input voltage range up to 40V.
Designed for ease of use, the LM2576S-5.0 includes features such as cycle-by-cycle current limiting and thermal shutdown for protection under fault conditions. It is available in a TO-263-5L surface mount package, suitable for various on-card switching regulator applications.
Applications include simple high-efficiency step-down regulators, efficient pre-regulators for linear regulators, and on-card switching power supplies.
