Instructions for Use:

1. Input Voltage (VIN): Ensure the input voltage is within the range of 4.5V to 36V. Exceeding these limits can damage the device.
2. Output Voltage (VOUT): The output voltage is fixed at 3.3V. No external components are required to set this voltage.
3. Output Current (IOUT): The device can provide up to 3A of continuous current. For applications requiring more than 2A, ensure adequate heat dissipation.
4. Efficiency (η): The typical efficiency is 92%. This can vary depending on the load and input voltage.
5. Switching Frequency (fSW): The switching frequency is fixed at 650kHz. This helps in reducing the size of external components.
6. Quiescent Current (IQ): The quiescent current is very low at 10μA, making the device suitable for battery-powered applications.
7. Dropout Voltage (VDROPOUT): The dropout voltage is 200mV, allowing the device to operate efficiently even when the input voltage is close to the output voltage.
8. Operating Temperature (TOPR): The device can operate in temperatures ranging from -40°C to 125°C. Ensure proper thermal management to avoid overheating.
9. Storage Temperature (TSTG): Store the device in temperatures between -40°C and 150°C.
10. Package Type: The device is available in a DFN package with dimensions of 3x3mm. Ensure the PCB layout is designed to accommodate this package.

Additional Notes:

• PCB Layout: Proper PCB layout is crucial for optimal performance. Keep traces short and wide to minimize resistance and inductance.
• Heat Dissipation: For high-current applications, consider adding a heatsink or using a PCB with a large copper area to dissipate heat.
• Capacitors: Use high-quality capacitors with low ESR for input and output filtering. Typical values are 10μF for input and 10μF for output.
• Inductor Selection: Choose an inductor with a saturation current rating higher than the maximum output current and a low DC resistance to minimize losses.
