Instructions for FAN6300AMY

1. Input Voltage (VIN):

   • Ensure the input voltage is within the range of 4.5V to 28V.
   • Avoid exceeding the maximum input current of 1.5A.

2. Output Voltage (VOUT):

   • Set the output voltage between 0.8V and 5.5V using external resistors.
   • Use the formula ( V_ = V_ times (1 + frac) ) to calculate the resistor values, where ( V_ ) is 0.8V.

3. Switching Frequency (fSW):

   • The switching frequency can be adjusted by selecting an appropriate external resistor.
   • The typical switching frequency is 600kHz, but it can range from 300kHz to 1500kHz.

4. Soft Start (SS):

   • The soft start time is typically 2.0ms but can be adjusted up to 4.0ms using an external capacitor.
   • Connect a capacitor between the SS pin and ground to set the soft start time.

5. Power Good Signal (PG):

   • The power good signal delay is typically 1.5ms but can be adjusted up to 3.0ms using an external capacitor.
   • Connect a capacitor between the PG pin and ground to set the delay.

6. Under-Voltage Lockout (UVLO):

   • The device will not operate if the input voltage drops below 2.8V.
   • The UVLO threshold is typically 3.2V.

7. Over-Voltage Protection (OVP):

   • The device will shut down if the output voltage exceeds 6.6V.
   • The OVP threshold is typically 7.0V.

8. Over-Temperature Protection (OTP):

   • The device will shut down if the internal temperature exceeds 150°C.
   • The OTP threshold is typically 160°C.

9. Enable Input (EN):

   • The enable input has a high threshold of 1.1V to 1.3V and a low threshold of 0.7V to 0.9V.
   • Apply a voltage higher than the high threshold to enable the device and lower than the low threshold to disable it.

10. Reference Voltage (VREF):

    • The reference voltage is typically 0.8V and can be used for setting the output voltage.

Ensure all connections are secure and follow the recommended layout guidelines to avoid issues with electromagnetic interference (EMI) and thermal management.
