概要
Description
The LM2576HVSX-ADJ is a high-voltage adjustable version of the LM2576 series of step-down (buck) voltage regulators. Designed for efficiency and simplicity, it can deliver an output current of up to 3A with minimal external components. This version is tailored for applications requiring input voltages as high as 60V, making it suitable for industrial, automotive, and telecom applications.
Key features include:
- Wide input voltage range up to 60V.
- Adjustable output voltage, allowing for flexibility in design.
- High efficiency, often above 80%, reducing heat and extending component life.
- Integrated switch to minimize external components, simplifying circuit design.
- Built-in thermal shutdown and current limit protection for increased reliability.
- Typically used in power supply circuits, battery chargers, and LED drivers.
The package style is typically TO-263 or similar, which aids in heat dissipation. Additionally, its frequency compensation is internal, making it easier to use compared to some other regulators that require external compensation networks.

Pinout
The LM2576HVSX-ADJ is a high-voltage adjustable version of the LM2576 series of monolithic integrated circuits designed for step-down switching regulators. It features a 5-pin package. The functions of these pins are as follows:
1. Vin (Pin 1): This is the input voltage pin through which the supply voltage is provided to the IC.
2. Output (Pin 2): This pin is the output of the regulator where the step-down voltage is obtained.
3. Ground (Pin 3): The ground pin serves as the common reference point for the input and output voltages.
4. Feedback (Pin 4): This pin is used to set the output voltage by connecting it to a resistor divider network from the output.
5. ON/OFF (Pin 5): This is the shutdown pin. A high voltage level turns the regulator off, while a low level enables normal operation.
The LM2576HVSX-ADJ is used for efficiently stepping down higher DC input voltages to a lower DC output voltage with adjustable output.
