Instructions for Use:

1. Input Voltage (VIN):

   • Ensure the input voltage is within the range of 4.5V to 17V.
   • Do not exceed the maximum input voltage to avoid damaging the device.

2. Output Voltage (VOUT):

   • The output voltage is fixed at 5.0V. No external components are required to set this voltage.

3. Output Current (IOUT):

   • The device can provide up to 5.0A of continuous output current.
   • Ensure that the load does not exceed this limit to prevent overheating or damage.

4. Efficiency (η):

   • The typical efficiency is 95%. This value may vary depending on the input voltage, output voltage, and load conditions.

5. Switching Frequency (fSW):

   • The switching frequency is fixed at 720kHz. This helps in reducing the size of external components like inductors and capacitors.

6. Quiescent Current (IQ):

   • The quiescent current is very low at 0.5mA, making the device suitable for low-power applications.

7. Load Regulation (ΔVOUT/ΔIOUT):

   • The load regulation is 0.5mV/A, indicating that the output voltage will change by 0.5mV for every 1A change in load current.

8. Line Regulation (ΔVOUT/ΔVIN):

   • The line regulation is 0.01mV/V, meaning the output voltage will change by 0.01mV for every 1V change in input voltage.

9. Dropout Voltage (VDROPOUT):

   • The dropout voltage is 0.5V, which is the minimum difference between the input and output voltages required for the regulator to maintain regulation.

10. Operating Temperature (Toperating):

    • The device can operate over a temperature range of -40°C to 125°C. Ensure that the ambient temperature and thermal design allow for proper heat dissipation.

11. Storage Temperature (Tstorage):

    • The device can be stored at temperatures ranging from -65°C to 150°C.

12. Package Type:

    • The LM73605RNPR is packaged in an 8-pin DFN (Dual Flat No-lead) package. Ensure proper handling and soldering techniques to avoid damage during assembly.

Additional Notes:

• PCB Layout:

  • Use a good thermal design to ensure efficient heat dissipation.
  • Place the input and output capacitors as close as possible to the device to minimize noise and improve stability.

• Capacitors:

  • Use high-quality ceramic capacitors for both input and output to ensure stable operation and low ESR (Equivalent Series Resistance).

• Inductor:

  • Choose an inductor with a saturation current rating higher than the maximum output current to avoid core saturation and potential failure.

• Protection:

  • The device includes built-in protection features such as overcurrent protection, thermal shutdown, and short-circuit protection. However, it is recommended to add external fuses or circuit breakers for additional safety.
