Instructions:

1. Power Connection:

   • Connect the input power supply to the Vin pin and GND.
   • Ensure the input voltage is within the specified range of 4.5V to 40V.

2. Output Configuration:

   • Adjust the output voltage by setting the external resistors connected to the FB1 and FB2 pins for each channel.
   • Use the formula provided in the datasheet to calculate resistor values based on desired output voltage.

3. Thermal Considerations:

   • Place the device on a heatsink or PCB with adequate copper area to dissipate heat if operating at higher currents or temperatures.

4. Protection Features:

   • The DAD2000 includes built-in overcurrent and thermal shutdown protections. No additional components are required for these features.

5. Layout Recommendations:

   • Keep the input capacitor close to the Vin and GND pins.
   • Ensure all connections are secure and insulated to prevent short circuits.

6. Testing:

   • After assembly, test the output voltages under load to ensure they meet specifications.
   • Verify that the overcurrent protection activates as expected when a fault condition is simulated.
