LM2576HVT-12/LF03 TI Simple Switcher | TO-220-5 | 12V Output, 3A Step-Down

Product Overview

The LM2576HVT-12/LF03 from Texas Instruments is a monolithic integrated circuit that provides all the active functions for a step-down (buck) switching regulator. It is capable of driving a 3A load with excellent line and load regulation. This device is available in a TO-220-5 package and is designed to minimize the number of external components, simplifying power supply design. The LM2576HVT-12/LF03 operates at a fixed switching frequency of 52 kHz, thus allowing smaller filter components than what would be needed with lower frequency switching regulators. The output voltage is fixed at 12V, making it ideal for a wide range of applications.
