Instructions

1. Power Supply Connection:

   • Connect the input power supply (VCC) to the designated pin.
   • Ensure the input voltage is within the specified range (2.5V to 5.5V).

2. Output Voltage Setting:

   • The output voltage (VOUT) can be adjusted using an external resistor network.
   • Use the formula provided in the datasheet to calculate the appropriate resistor values.

3. Output Load Connection:

   • Connect the load to the output pins (VOUT and GND).
   • Ensure the load current does not exceed the maximum continuous output current (3.0A).

4. Switching Frequency Adjustment:

   • The switching frequency (fSW) can be adjusted by connecting an external resistor to the FREQ pin.
   • Refer to the datasheet for the specific resistor values and corresponding frequencies.

5. Thermal Management:

   • Ensure proper heat dissipation by mounting the device on a heatsink or PCB with adequate copper area.
   • Monitor the operating temperature to ensure it stays within the specified range (-40°C to 85°C).

6. Shutdown Mode:

   • To put the device into shutdown mode, pull the SHDN pin low.
   • The shutdown current (ISD) is typically 1μA.

7. Capacitor Selection:

   • Use recommended input and output capacitors as specified in the datasheet to ensure stable operation.
   • Input capacitors should be placed close to the VCC pin to minimize noise.

8. PCB Layout:

   • Follow the recommended PCB layout guidelines to minimize parasitic inductance and ensure optimal performance.
   • Keep the ground plane solid and connect all ground pins directly to the ground plane.

9. Storage and Handling:

   • Store the device in a dry environment within the specified storage temperature range (-55°C to 125°C).
   • Handle the device with care to avoid damage from static electricity.
