Instructions for Use

1. Input Voltage (V_IN):

   • Ensure the input voltage is within the range of 4.5V to 28V.
   • Avoid exceeding the maximum input voltage to prevent damage to the device.

2. Output Voltage (V_OUT):

   • Set the output voltage using the feedback resistor network.
   • The output voltage can be adjusted between 0.8V and 5.5V.

3. Output Current (I_OUT):

   • The device can provide a continuous output current up to 5A.
   • For reliable operation, ensure the load does not exceed the maximum rated current.

4. Switching Frequency (f_SW):

   • The switching frequency is fixed at 1.2MHz.
   • This frequency helps in reducing the size of external components like inductors and capacitors.

5. Efficiency (η):

   • The efficiency is typically 93% at 5V input, 3.3V output, and 1A load.
   • Efficiency can vary with different input and output conditions.

6. Quiescent Current (I_Q):

   • The quiescent current is typically 25μA when there is no load.
   • This low quiescent current helps in extending battery life in portable applications.

7. Shutdown Current (I_SD):

   • When the enable pin (V_EN) is set to 0V, the shutdown current is typically 1μA.
   • Use this feature to conserve power when the device is not in use.

8. Dropout Voltage (V_DO):

   • The dropout voltage is typically 200mV at a 1A load.
   • This low dropout voltage allows the device to operate efficiently even when the input voltage is close to the output voltage.

9. Operating Temperature (T_OP):

   • The operating temperature range is from -40°C to 125°C.
   • Ensure the device operates within this temperature range to avoid thermal stress and potential damage.

10. Storage Temperature (T_STG):

    • The storage temperature range is from -65°C to 150°C.
    • Store the device in a dry place within this temperature range to maintain its performance and reliability.
