Instructions for Using the FAN6862TY

1. Input Voltage (VIN):

   • Ensure the input voltage is within the range of 4.5V to 28V.
   • Use appropriate filtering capacitors to stabilize the input voltage.

2. Output Voltage (VOUT):

   • Set the output voltage using external resistors according to the formula: [ V_ = 0.8 left(1 + fracright) ]
   • Choose R1 and R2 to achieve the desired output voltage.

3. Output Current (IOUT):

   • The maximum output current is 2.5A. Ensure the load does not exceed this limit to avoid damage.
   • Use an appropriate inductor and output capacitor to maintain stability under varying loads.

4. Switching Frequency:

   • The switching frequency can be set by an external resistor connected to the RT/CLK pin.
   • Use the following formula to calculate the resistor value: [ f_ = frac{1.1}{R_ times 10^{-6}} ]

5. Duty Cycle:

   • The duty cycle should be between 0.3 and 0.9 to ensure proper operation.
   • Adjust the feedback network to maintain the desired duty cycle.

6. Quiescent Current:

   • The quiescent current is typically 3.5mA but can go up to 10mA.
   • This current is drawn from the input supply and should be considered in power budget calculations.

7. Dropout Voltage:

   • The dropout voltage is typically 1.2V. Ensure the input voltage is at least 1.2V higher than the output voltage to maintain regulation.

8. Operating Temperature:

   • The device operates reliably between -20°C and 85°C.
   • Avoid operating the device outside this range to prevent thermal stress and potential failure.

9. Storage Temperature:

   • Store the device between -65°C and 150°C to ensure long-term reliability.

10. Package:

    • The FAN6862TY is available in an SO-8 package.
    • Follow standard PCB layout guidelines for thermal management and signal integrity.

Additional Notes:

• Always refer to the datasheet for detailed information and specific application notes.
• Use appropriate decoupling capacitors near the power pins to reduce noise and improve stability.
• Ensure proper heat dissipation if operating at high output currents or in high ambient temperatures.
