LM2575, NCV2575

1.0 A, Adjustable Output

Voltage, Step-Down

Switching Regulator

The LM2575 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 1.0 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.

TO−220

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 LM2575 are offered by several

different inductor manufacturers.

Since the LM2575 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 by the LM2575 regulator is so

low, that no heatsink is required or its size could be reduced

dramatically.

The LM2575 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.
