Instructions for Use:
Input Connection:
- Connect the input voltage (3.3V to 5.5V) to the VIN pin.
- Ensure the input voltage is within the specified range to avoid damage.
Output Configuration:
- Set the desired output voltage using the external feedback resistor network connected to the FB pin.
- Refer to the datasheet for specific resistor values to achieve the required output voltage.
Output Connection:
- Connect the load to the VOUT pin.
- Ensure the load does not exceed the maximum output current (3.0A).
Ground Connection:
- Connect the ground (GND) pin to the common ground of the system.
Capacitor Selection:
- Use a ceramic capacitor (10μF to 22μF) on the input side for filtering.
- Use a ceramic capacitor (10μF to 22μF) on the output side for stability and ripple reduction.
Thermal Management:
- Ensure adequate heat dissipation by providing a heat sink or placing the IC in an area with good airflow.
- Monitor the operating temperature to prevent thermal shutdown.
Protection Circuits:
- The device includes short-circuit protection and thermal shutdown features.
- In case of a short circuit, the device will automatically limit the current and recover once the fault is cleared.
Start-up Sequence:
- The device will start up and stabilize the output voltage within 1.0 to 2.0 milliseconds after power-on.
Storage and Handling:
- Store the device in a dry, cool place within the specified storage temperature range.
- Handle with care to avoid static discharge and physical damage.
For detailed information, refer to the datasheet provided by the manufacturer.
