Instructions for VIPER26L
Input Voltage Connection:
- Connect the input voltage between VIN and GND, ensuring it is within the specified range (8V to 40V).
Output Configuration:
- The device provides a fixed output voltage of 5V. Ensure your circuit design can handle this output voltage.
Capacitor Selection:
- Choose input and output capacitors that are stable over the operating temperature range and meet the ripple current requirements.
Inductor Selection:
- Select an inductor that can handle the maximum output current (260mA) without saturating.
Thermal Considerations:
- Ensure adequate heat dissipation to maintain the junction temperature within safe limits.
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.
Protection Circuits:
- Implement necessary protection circuits such as reverse polarity protection, transient voltage suppression, and overcurrent protection.
Testing and Validation:
- After assembly, test the power supply under various load conditions to ensure stability and performance meet specifications.
