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
