Pinout
The LM2575HVT-15 is a voltage regulator IC with 5 pins. It is part of the LM2575 series, which are step-down (buck) switching regulators. The device is designed to provide a fixed output voltage of 15V and can deliver up to 1A of output current, making it suitable for a variety of power supply applications.
Here is a brief overview of the pin functions:
1. Vin: This is the input voltage pin where the unregulated input supply voltage is connected. It can accept a wide range of input voltages higher than the desired output voltage.
2. Output: This pin is the regulated output voltage. It is where the load is connected to receive the fixed 15V output.
3. Ground: This is the ground reference pin for the input and output voltages. It is connected to the system ground.
4. Feedback: This pin is used to sense the output voltage and maintain regulation. In the fixed version of the LM2575, it is internally connected.
5. ON/OFF: This pin enables or disables the regulator. Connecting it to ground turns the regulator on, while a high voltage turns it off. This feature is useful for power-saving applications.
