LM2576HVS-ADJ Products

The LM2576HVS-ADJ series of regulators are monolithic integrated circuits that provide all theactive functions for a step-down (buck) switching regulator, capable of driving 3-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 fault protection and a fixed-frequency oscillator.

The LM2576HVS-ADJ series offers a high-efficiency replacement for popular three-terminal linearregulators. It substantially reduces the size of the heat sink, and in some cases no heat sink isrequired.

A standard series of inductors optimized for use with the LM2576HVS-ADJ are available fromseveral different manufacturers. This feature greatly simplifies the design of switch-mode powersupplies.

Other features include a ±4% tolerance on output voltage within specified input voltagesand 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 currentlimiting, as well as thermal shutdown for full protection under fault conditions.

Feature

  • 3.3-V, 5-V, 12-V, 15-V, and Adjustable Output Versions
