Instructions for Using MC33063AVDR2G

1. Input Voltage (V_IN):

   • Ensure the input voltage is within the range of 3.0V to 40V.
   • Use appropriate input capacitors to stabilize the input voltage.

2. Output Voltage (V_OUT):

   • The output voltage can be adjusted using external resistors R1 and R2.
   • Use the formula: V_OUT = 1.25 * (1 + R2/R1) + I_ADJ * R2, where I_ADJ is typically 50μA.

3. Switching Frequency (f_SW):

   • The switching frequency can be set by connecting an external resistor (R_FREQ) between the FREQ/SHDN pin and ground.
   • Use the formula: f_SW = 184320 / R_FREQ, where R_FREQ is in ohms.

4. Maximum Output Current (I_OUT):

   • The maximum output current is 1.5A. Ensure the inductor and other components can handle this current.

5. Quiescent Current (I_Q):

   • The quiescent current is typically 2.5mA. This is the current consumed by the IC when it is active but not delivering power to the load.

6. Shutdown Current (I_SD):

   • When the FREQ/SHDN pin is pulled low, the IC enters shutdown mode, and the shutdown current is typically 0.1μA.

7. Output Voltage Accuracy (ΔV_OUT):

   • The output voltage accuracy is ±1.5%. Ensure that the resistors used for feedback are precision components to achieve this accuracy.

8. Operating Temperature Range (T_A):

   • The IC operates reliably within the temperature range of -40°C to 125°C.

9. Storage Temperature Range (T_STG):

   • Store the IC in a temperature range of -65°C to 150°C to ensure long-term reliability.

10. Junction Temperature (T_J):

    • The maximum junction temperature is 150°C. Ensure proper heat dissipation if the IC is operating at high power levels.

Additional Notes:

• Always refer to the datasheet for detailed information and specific application circuits.
• Use appropriate PCB layout techniques to minimize noise and improve performance.
• Ensure all components are rated for the expected operating conditions.
