Description for the LM2574

The LM2574xx series of regulators are monolithic integrated circuits that provide all theactive functions for a step-down (buck) switching regulator, capable of driving a 0.5-A load withexcellent 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 andinclude internal frequency compensation and a fixed-frequency oscillator.

The LM2574xx series offers a high-efficiency replacement for popular three-terminallinear 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 fromseveral different manufacturers. This feature greatly simplifies the design of switch-mode powersupplies.

Other features include a specified ±4% tolerance on output voltage within specified inputvoltages and output load conditions, and ±10% on the oscillator frequency. External shutdown isincluded, featuring 50-µA (typical) standby current. The output switch includes cycle-by-cyclecurrent limiting, as well as thermal shutdown for full protection under fault conditions.

The TPS560430 isa newer generation buck converter, being functionally equivalent to LM2574. It offers reduced BOMcost, increased efficiency, and reduced solution size. See the Device Comparison Table to comparespecifications.StartWEBENCH Design with TPS560430.

Carrier options

You can choose different carrier options based on the quantity of parts, including full reel, custom reel, cut tape, tube or tray.

custom reel is a continuous length of cut tape from one reel to maintain lot- and date-code traceability, built to the exact quantity requested. Following industry standards, a brass shim connects an 18-inch leader and trailer on both sides of the cut tape for direct feeding into automated assembly machines. TI includes a reeling fee for custom reel orders.

Cut tape is a length of tape cut from a reel. TI may fulfill orders using multiple strips of cut tapes or boxes to satisfy the quantity requested.

TI often ships  tube or tray  devices inside a box or in the tube or tray, depending on inventory availability. We pack all tapes, tubes or sample boxes according to internal electrostatic discharge and moisture-sensitivity-level protection requirements.
