Datasheet

LM2575SX-5.0/NOPB – High-Efficiency 5V 1A Buck Switching Regulator IC

The LM2575SX-5.0/NOPB is a monolithic integrated buck switching regulator designed for efficiency, reliability, and simplicity. This IC efficiently converts higher DC voltages down to a regulated 5V output while supporting load currents up to 1A. It integrates all active functions required for a step-down regulator, minimizing the need for external components. The internal fixed-frequency oscillator and frequency compensation ensure stable performance across line and load variations. Its efficiency significantly reduces power loss compared to traditional linear regulators, minimizing the need for heat sinks. Designed for compactness, performance, and protection, the LM2575SX-5.0/NOPB is ideal for industrial, automotive, and general-purpose DC-DC converter applications.

Key Features
