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 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.

Since the LM2576 converter is a switch-mode power supply, its efficiency is significantly higher in comparison

with popular three-terminal linear regulators, especially with higher input voltages.

In many cases, the power dissipated is so low that no heatsink is required or its size could be reduced

dramatically. A standard series of inductors optimized for use with the LM2576 are available from several

different manufacturers. This feature greatly simplifies the design of switch-mode power supplies. The LM2576

features include a guaranteed +/- 4% tolerance on output voltage within specified input voltages and output

load conditions, and +/-10% on the oscillator frequency (+/- 2% over 0˚C to 125˚C).

External shutdown is included, featuring 80㎂(typical) standby current. The output switch includes cycle-

bycycle current limiting, as well as thermal shutdown for full protection under fault conditions.
