LM2576x SIMPLE SWITCHER® Voltage Regulators

Texas Instruments LM2576x SIMPLE SWITCHER® Voltage Regulators are monolithic integrated circuits that provide all the active functions for a step-down (buck) switching regulator. These regulators can drive a 3A load with excellent line and load regulation. The LM2576x devices are available in fixed output voltages of 3.3V, 5V, 12V, 15V, and an adjustable output version. The Texas Instruments LM2576x voltage regulators offer a high-efficiency replacement for popular three-terminal linear regulators. These voltage regulators feature high-efficiency TTL shutdown capability and dramatically simplify switch-mode power supply design.
