DC Switching Voltage Regulators

LM2576HVT-12/NOPB Description

The LM2576HVT-12/NOPB is a fixed 12V, 3A step-down (buck) switching voltage regulator from Texas Instruments' SIMPLE SWITCHER® series. Designed for high-efficiency power conversion, it accepts a wide input voltage range of 4V to 60V, making it suitable for industrial, automotive, and telecom applications where input voltage fluctuations are common. The regulator operates at a 52kHz switching frequency, balancing efficiency and noise performance. Housed in a TO-220-5 through-hole package, it is robust and easy to integrate into designs requiring high current output with minimal external components.

LM2576HVT-12/NOPB Features

• Fixed 12V Output: Eliminates the need for external feedback resistors, simplifying design.
• High Input Voltage (60V Max): Ideal for applications with unregulated or variable power sources.
• 3A Output Current: Supports high-power loads without external pass transistors.
• 52kHz Switching Frequency: Reduces inductor size while maintaining low EMI.
• Non-Synchronous Rectification: Cost-effective for moderate-efficiency applications.
• Thermal Shutdown & Current Limiting: Protects against overloads and overheating.
• ROHS3 Compliant & REACH Unaffected: Meets environmental and safety standards.
• Wide Operating Temperature Range: Suitable for harsh environments.
