LM2576HVT-ADJ/LF03 TI SIMPLE SWITCHER® Regulator | TO-220-5 | 3A, 60V, Adjustable

Product Overview

The LM2576HVT-ADJ/LF03 from Texas Instruments is a high-voltage, adjustable output version of the LM2576 series SIMPLE SWITCHER® step-down voltage regulator. It provides all active functions for a step-down (buck) switching regulator, capable of driving a 3A load with excellent line and load regulation. The device is available in a TO-220-5 package and operates over a wide input voltage range up to 60V. With a fixed switching frequency of 52 kHz, it offers high efficiency and requires only a minimum number of external components. The LM2576HVT-ADJ/LF03 features internal frequency compensation, a fixed-frequency oscillator, cycle-by-cycle current limiting, and thermal shutdown for protection.
