Instructions for Use:

1. Input Connection:

   • Connect the input power supply to the VIN and GND pins.
   • Ensure the input voltage is within the specified range (4.5V to 28V).

2. Output Configuration:

   • Adjust the output voltage using the feedback resistor network connected to the ADJ pin.
   • The output voltage can be calculated using the formula: Vout = 1.23V * (1 + R2/R1), where R1 and R2 are the resistors connected to the ADJ pin.

3. Enable Control:

   • To enable or disable the converter, apply a high or low signal to the EN pin.
   • A high signal (greater than 1.2V) enables the converter, while a low signal (less than 0.8V) disables it.

4. Thermal Management:

   • Ensure adequate heat dissipation, especially when operating at high output currents.
   • Consider using a heatsink if the converter is expected to operate at or near its maximum current capacity.

5. Protection:

   • The converter includes overcurrent and overvoltage protection features.
   • In the event of an overcurrent condition, the converter will automatically shut down to prevent damage.

6. Soft Start:

   • The soft start feature reduces inrush current and prevents voltage overshoot during startup.
   • The soft start time is typically 1ms.

7. Storage:

   • Store the device in a dry, cool environment to prevent damage from moisture or extreme temperatures.
