Instructions for Use

1. Input Capacitor Selection:

   • Use a ceramic capacitor with X5R or X7R dielectric.
   • Recommended value: 1 渭F to 10 渭F.
   • Ensure the capacitor has a voltage rating higher than the maximum input voltage.

2. Output Capacitor Selection:

   • Use a ceramic capacitor with X5R or X7R dielectric.
   • Recommended value: 4.7 渭F to 10 渭F.
   • Ensure the capacitor has a voltage rating higher than the output voltage.

3. Inductor Selection:

   • Choose an inductor with a saturation current higher than the maximum output current.
   • Recommended value: 2.2 渭H to 4.7 渭H.
   • Ensure the inductor has a low DC resistance (DCR) to minimize power loss.

4. PCB Layout:

   • Place the input and output capacitors as close as possible to the TPS61170DRVR.
   • Keep the ground plane solid and wide to ensure good thermal performance.
   • Use short and wide traces for high current paths.

5. Thermal Management:

   • Ensure adequate heat dissipation by using a large copper area on the PCB.
   • Consider adding a heatsink if operating at high temperatures or high output currents.

6. Shutdown Function:

   • Connect the SHDN pin to GND to turn off the device.
   • Connect the SHDN pin to VIN to enable the device.
   • The shutdown current is very low, making it suitable for battery-powered applications.

7. Stability:

   • The TPS61170DRVR is internally compensated and does not require external compensation components.
   • Ensure the recommended component values and types are used to maintain stability.

8. Handling Precautions:

   • Handle the device with care to avoid damage from electrostatic discharge (ESD).
   • Follow proper soldering techniques to avoid thermal stress on the device.

By following these guidelines, you can ensure optimal performance and reliability of the TPS61170DRVR in your application.
