LM2576R-3.3 Description

Short technical summary and product information.

The LM2576R-3.3 from HTC is a monolithic integrated circuit designed for easy and convenient implementation of step-down switching regulators (buck converters). This device is capable of driving a 3.0A load with excellent line and load regulation, providing a fixed 3.3V output.

 

Key electrical specifications include a guaranteed 3.0A output current and a fixed 52kHz internal oscillator frequency. It features a wide input voltage range and requires only four external components for operation, simplifying power supply design. The regulator includes essential protection features such as thermal shutdown and current limit protection for enhanced reliability.

 

This component is suitable for applications requiring high-efficiency step-down conversion. Its switch-mode design offers significantly higher efficiency compared to linear regulators, especially at higher input voltages, potentially reducing or eliminating the need for a heatsink. The TO-263-5L package is designed for surface mounting.

 

The LM2576 series is also available in other fixed output voltages (5.0V, 12V, 15V) and an adjustable version. Standard inductors optimized for use with the LM2576 are readily available from multiple manufacturers.
