LM2576

3.0 A, 15 V, Step−Down

Switching Regulator

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 3.0 A load with excellent line and load regulation.

These devices are available in fixed output voltages of 3.3 V, 5.0 V,

12 V, 15 V, 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.

Heatsink surface connected to Pin 3

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 mA (typical) standby current. The

output switch includes cycle−by−cycle current limiting, as well as

thermal shutdown for full protection under fault conditions.
