Instructions:
- Input Connection: Connect the input voltage within the specified range (4.5V to 28V) to the VIN pin.
- Output Configuration: Set the desired output voltage using external resistors connected to the FB pin according to the datasheet formula.
- Inductor Selection: Choose an inductor based on the switching frequency and output current requirements.
- Capacitor Selection: Select input and output capacitors that can handle the ripple current and provide stable operation.
- Thermal Considerations: Ensure adequate heat dissipation if operating at high currents or temperatures.
- Layout Guidelines: Follow recommended PCB layout guidelines for optimal performance and noise reduction.
- Power-Up Sequence: Apply power gradually to avoid inrush currents and ensure stable startup.
