1. Understand the Pin Configuration:
   • L1 and L2: These are the pins for the inductor connection. A power inductor will be connected between these two pins.
   • VIN: The input voltage pin where you'll apply your source voltage.
   • GND: Ground connection for the converter.
   • EN: Enable pin. Driving this pin high will enable the converter.
   • ILIM0 and ILIM1: These pins are used to set the current limit.
   • SS: Soft-start pin. A capacitor connected here will control the startup time.
   • FB: Feedback pin for output voltage regulation. Connect a resistor divider or directly to VOUT for fixed output voltage models.
   • VOUT: The output voltage pin which provides the regulated voltage.
   • PG: Power good pin, indicating when the output is within regulation.
   • PFM/PWM: Select between pulse frequency modulation and pulse width modulation using this pin.
2. Select the Necessary External Components:
   • Inductor: Choose an appropriate value, usually found in the datasheet, based on your input and output voltage and current requirements.
   • Capacitors: Place input and output capacitors to stabilize the input and output voltage. Their size and type depend on your application's specific requirements.
   • Resistor Divider for FB: If using it in adjustable mode, calculate the resistor values to achieve the desired output voltage.
3. Make Connections:
   • Connect Inductor:
     • Connect $U1:L1$ to one terminal of the inductor.
     • Connect $U1:L2$ to the other terminal of the inductor.
   • Connect Power Input:
     • Connect the positive side of your power source to $U1:VIN$.
   • Connect Ground:
     • Connect $U1:GND$ to the ground of your circuit.
   • Enable Pin:
     • Pull $U1:EN$ high to enable the device. You might use a pull-up resistor to VIN.
   • Soft-start Capacitor:
     • Connect a capacitor between $U1:SS$ and ground to set the soft-start time.
   • Feedback Network:
     • Connect a resistor network between $U1:FB$, $U1:VOUT$, and ground to set the output voltage.
   • VOUT Connection:
     • Connect $U1:VOUT$ to your load.
   • PFM/PWM Selection:
     • Connect this pin to either a logic high (typically VIN) or low (ground) based on your desired control method.
4. Performance Verification:
   • Test the circuit under expected load conditions to ensure the output voltage remains stable and within specifications.
