Description

The LM2574xx series of regulators are monolithic

integrated circuits that provide all the active functions

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

driving a 0.5-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 internal frequency compensation and a fixed-

frequency oscillator. The LM2574xx series offers a

high-efficiency replacement for popular three-terminal

linear regulators. Because of its high efficiency, the copper

traces on the printed-circuit board (PCB) are normally

the only heat sinking needed.

A standard series of inductors optimized for use with

the LM2574 are available from several different

manufacturers. This feature greatly simplifies the

design of switch-mode power supplies.

Other features include a specified ±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 TPS560430 is a newer generation buck

converter, being functionally equivalent to LM2574. It

offers reduced BOM cost, increased efficiency, and

reduced solution size. See the Device Comparison

Table to compare specifications. Start WEBENCH

Design with TPS560430.
