Instructions for VIPER26L

1. Input Voltage Connection:

   • Connect the input voltage between VIN and GND, ensuring it is within the specified range (8V to 40V).

2. Output Configuration:

   • The device provides a fixed output voltage of 5V. Ensure your circuit design can handle this output voltage.

3. Capacitor Selection:

   • Choose input and output capacitors that are stable over the operating temperature range and meet the ripple current requirements.

4. Inductor Selection:

   • Select an inductor that can handle the maximum output current (260mA) without saturating.

5. Thermal Considerations:

   • Ensure adequate heat dissipation to maintain the junction temperature within safe limits.

6. Layout Recommendations:

   • Keep the layout compact with short traces, especially for high-frequency switching nodes.
   • Place bypass capacitors close to the IC to minimize noise.

7. Protection Circuits:

   • Implement necessary protection circuits such as reverse polarity protection, transient voltage suppression, and overcurrent protection.

8. Testing and Validation:

   • After assembly, test the power supply under various load conditions to ensure stability and performance meet specifications.
