The LM2575HVN-5.0, manufactured by Texas Instruments, is a monolithic integrated circuit that provides all the active functions for a step-down (buck) switching regulator capable of driving a 1A load with excellent line and load regulation. This voltage regulator is particularly suited for easy and efficient power conversion, reducing the input voltage to a lower, regulated 5V output.

Key Features

• Output Voltage: Fixed 5V output with a tolerance of ±4% over line and load conditions.
• Current Output: Capable of delivering 1A output current.
• High Efficiency: Utilizes a simple external inductor and diode to achieve high efficiency over a wide range of load conditions, with up to 52% efficiency at 1A load current.
• Thermal Shutdown and Current Limit Protection: In-built safety features that protect the device and the load under abnormal conditions.
• Wide Input Voltage Range: Operates from a 4.75V to 60V input, making it suitable for a broad range of applications.
• 52kHz Fixed Frequency Internal Oscillator: The fixed frequency simplifies noise filtering in sensitive applications.

Applications

The LM2575HVN-5.0 is versatile and can be used in a variety of applications, including:

• Simple high-efficiency step-down (buck) regulators.
• Efficient pre-regulators for linear regulators.
• On-card switching regulators.
• Positive to negative converter (Buck-Boost).
