3. Output Current: Capable of delivering up to 3A continuous output current.
4. Efficiency: High efficiency, typically around 90%.
5. Switching Frequency: Fixed switching frequency of 150 kHz.
6. Thermal Protection: Built-in thermal shutdown to prevent overheating.
7. Short-Circuit Protection: Protects against overload conditions.
8. Voltage Regulation: Offers good line and load regulation.
9. Component Integration: Reduces the need for external components, simplifying design.
These features make the LM2596SX-12 ideal for powering various electronic applications requiring a stable 12V output from a higher DC input.
Pinout
1. VIN (Input Voltage): This pin is where the input voltage is provided, ranging typically from 4.5V to 40V for the LM2596 series.
2. Output: This pin is the regulated output voltage pin and provides the fixed 12V output.
3. Ground (GND): This is the ground reference pin for the input and output voltages.
4. Feedback (FB): For the adjustable version, this pin is used to set the output voltage. However, in the fixed variant like the LM2596SX-12, it is internally set and not used externally for adjustments.
5. ON/OFF (SD - Shutdown): This pin is used to enable or disable the regulator. Connecting this pin to a high logic level turns the regulator off, while a low logic level turns it on.
These pins enable the LM2596SX-12 to efficiently convert higher input voltages into a stable 12V output, suitable for various electronic applications.
