Instructions:

1. Power Supply Connection: Connect the input voltage between VIN and GND pins. Ensure the input voltage is within the specified range.
2. Output Configuration: Set the desired output voltage using an external resistor network connected to FB pin.
3. Capacitors: Place input and output capacitors close to the respective pins to ensure stability and reduce noise.
4. Inductor Selection: Choose an inductor that can handle the maximum output current with minimal ripple.
5. Thermal Management: Ensure adequate heat dissipation if operating near the maximum output current or in high ambient temperatures.
6. Shutdown Feature: To put the device into a low-power state, pull the EN pin low. Return it high to resume normal operation.
7. PCB Layout: Follow good PCB layout practices to minimize EMI and ensure reliable operation. Keep traces short and direct, especially for high-frequency nodes.
