DESCRIPTION:
- The LM2576 series of regulators are monolithic integrated circuits ideally suited for easy and convenient design of a step-down switching regulator (buck converter).
- All circuits of this series are capable of driving a 3.0A load with excellent line and load regulation. These devices are available in fixed output voltages of 3.3V, 5.0V, 12V, 15V, and an adjustable output version.
- These regulators were designed to minimize the number of external components to simplify the power supply design.
- Standard series of inductors optimized for use with the LM2576 are offered by several different inductor manufacturers.
