Instructions for TPS61194PWPRQ1:

1. Power Supply Connection:

   • Connect the input voltage (VIN) to the power supply ensuring it is within the specified range of 1.8V to 5.5V.

2. Output Configuration:

   • The device provides fixed output voltages of 3.3V and 5V. Ensure the selected output voltage matches your system requirements.

3. Capacitor Selection:

   • Choose input and output capacitors based on the datasheet recommendations to ensure stability and performance.

4. Inductor Selection:

   • Select an appropriate inductor value as per the datasheet guidelines to optimize efficiency and minimize ripple.

5. Thermal Considerations:

   • Ensure adequate thermal management by following the recommended PCB layout and considering the ambient temperature.

6. Enable/Shutdown Control:

   • Use the enable pin to control the operation of the device. Pulling this pin low will put the device into a low-power shutdown mode.

7. Bypass Capacitors:

   • Place bypass capacitors close to the power and ground pins to reduce noise and improve transient response.

8. Layout Guidelines:

   • Follow the recommended PCB layout from the datasheet to ensure optimal performance and reliability.

Note: Detailed specifications and more precise instructions can be found in the official datasheet provided by the manufacturer.
