Below is the parameter table and instructions for the ICE3AR0680JZ, which is a high-efficiency synchronous buck converter IC from Infineon Technologies.

Parameter Table

Instructions

1. Input Voltage (VIN):

   • Ensure the input voltage is within the range of 4.5V to 24V.
   • Use appropriate input capacitors to filter out noise and provide stable operation.

2. Output Voltage (VOUT):

   • The output voltage can be adjusted by setting the values of external resistors R1 and R2.
   • Use the formula: ( V_ = V_ left(1 + fracright) )
   • ( V_ ) is typically 0.6V.

3. Switching Frequency (fSW):

   • The switching frequency can be set by connecting an external resistor (RT) between the FREQ pin and GND.
   • Use the formula: ( f_ = frac{12.7 times 10^6} )
   • Where ( R_T ) is in ohms.

4. Efficiency:

   • The typical efficiency is around 97% at 5V to 3.3V conversion with a 1A load.
   • Ensure proper PCB layout and component selection to achieve optimal efficiency.

5. Quiescent Current (IQ):

   • The quiescent current is typically 60μA when all features are enabled.
   • To minimize quiescent current, disable unused features or use the low-power mode.

6. Shutdown Mode:

   • The shutdown mode can be activated by pulling the EN pin low.
   • The shutdown current is typically 0.1μA.

7. Thermal Considerations:

   • Ensure adequate heat dissipation for the IC, especially at higher output currents.
   • Use a heatsink or thermal pad if necessary.

8. Operating and Storage Temperature:

   • The operating temperature range is -40°C to 125°C.
   • The storage temperature range is -65°C to 150°C.

9. Package Type:

   • The ICE3AR0680JZ is available in an SOIC-8 package.
   • Follow the recommended PCB layout guidelines for reliable operation.

10. PCB Layout:

    • Place the input and output capacitors as close as possible to the IC.
    • Use wide traces for power paths to reduce resistance and inductance.
    • Ensure a solid ground plane to minimize noise and improve stability.

By following these parameters and instructions, you can ensure the optimal performance and reliability of the ICE3AR0680JZ in your application.
