3 Description

The LM2576 series of regulators are monolithic

integrated circuits that provide all the active functions

for a step-down (buck) switching regulator, capable

of driving 3-A load with excellent line and load

regulation. These devices are available in fixed output

voltages of 3.3 V, 5 V, 12 V, 15 V, and an adjustable

output version.

Requiring a minimum number of external

components, these regulators are simple to use

and include fault protection and a fixed-frequency

oscillator.

The LM2576 series offers a high-efficiency

replacement for popular three-terminal linear

regulators. It substantially reduces the size of the heat

sink, and in some cases no heat sink is required.

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.

Other features include a ±4 tolerance on output

voltage within specified input voltages and output

load conditions, and ±10 on the oscillator frequency.

External shutdown is included, featuring 50-μA

(typical) standby current. The output switch includes

cycle-by-cycle current limiting, as well as thermal

shutdown for full protection under fault conditions.

The LM76003 requires very few external components

and has a pinout designed for simple, optimum PCB

layout for EMI and thermal performance. See the

device comparison table to compare specs.
