Product Overview

The LM2576HVT-5.0/NOPB is a monolithic integrated circuit that provides all active functions for a step-down buck switching regulator, capable of driving a 3A load with excellent line and load regulation. This high-voltage version operates with input voltages up to 60V, converting high input levels efficiently down to a fixed output of 5.0V. Requiring a minimal number of external components, this regulator simplifies power supply design while maximizing conversion efficiency compared to traditional linear regulators.

Key Features and Specifications

Featuring an internal 52 kHz oscillator, the LM2576HVT-5.0/NOPB drastically reduces the size of external filter components. It includes internal frequency compensation, thermal shutdown protection, and current limit protection to ensure safe and reliable operation in demanding environments. The device accepts input voltages ranging from 7V to 60V and features an ON/OFF control pin to enable low-power standby modes.

Applications and Package

Housed in a standard 5-lead TO-220 bent/staggered lead package (HVT), this component is ideal for high-efficiency step-down buck converters, pre-regulators for linear supplies, efficient switch-mode power sources, and battery chargers. Its robust power dissipation capabilities and straightforward circuit footprint make it a staple in industrial control, automotive power, and embedded electronics design.
