LM2576HVSX-12 Function Overview

●Description

●The LM2576 series of regulators are monolithic integrated circuits that provide all the active functions

●for a step-down (buck) switching regulator, capable of driving 3-A load with excellent 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.

●Features

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

●• Adjustable Version Output Voltage Range,1.23 V to 37 V (57 V for HV Version) ±4% Maximum Over Line and Load Conditions

●• Specified 3-A Output Current

●• Wide Input Voltage Range: 40 V Up to 60 V for HV Version

●• Requires Only 4 External Components

●• 52-kHz Fixed-Frequency Internal Oscillator

●• TTL-Shutdown Capability, Low-Power Standby Mode

●• High Efficiency

●• Uses Readily Available Standard Inductors

●• Thermal Shutdown and Current Limit Protection

●Applications

●• Simple High-Efficiency Step-Down (Buck) Regulator

●• Efficient Preregulator for Linear Regulators

●• On-Card Switching Regulators

●• Positive-to-Negative Converter (Buck-Boost)
