Instructions for Using VIPER100A-E

1. Input Connection:

   • Connect the input voltage (V_IN) to the VIN pin.
   • Ensure the input voltage is within the range of 8V to 40V.

2. Output Configuration:

   • Set the output voltage (V_OUT) using external resistors connected to the FB (Feedback) pin.
   • The output voltage can be adjusted between 3.3V and 15V.

3. Output Load:

   • The maximum continuous output current is 1.5A.
   • For optimal performance, keep the load current below 1A.

4. Switching Frequency:

   • The switching frequency is fixed at 100kHz.
   • This helps in minimizing the size of external components like inductors and capacitors.

5. Thermal Management:

   • Monitor the operating temperature to ensure it does not exceed 125°C.
   • Use a heatsink if necessary to dissipate heat, especially under high load conditions.

6. Protection Features:

   • The device includes thermal shutdown protection, which activates at approximately 160°C.
   • Ensure proper ventilation and cooling to prevent thermal shutdown.

7. Quiescent Current:

   • The quiescent current is typically 100μA, which helps in maintaining high efficiency even at light loads.

8. Start-up Current:

   • The start-up current is typically 10mA, which is required to initialize the internal circuits.

9. Storage Conditions:

   • Store the device in a dry environment with temperatures between -40°C and 150°C.

10. Package Handling:

    • Handle the SOIC-8 package with care to avoid damage to the pins.
    • Follow standard ESD (Electrostatic Discharge) precautions when handling the device.

By following these instructions, you can ensure reliable and efficient operation of the VIPER100A-E.
