Instructions

1. Power Supply Connection:

   • Connect the input voltage (VIN) to the power supply within the range of 2.95V to 5.5V.
   • Ensure that the input capacitor (CIN) is placed close to the VIN pin to minimize noise and improve stability.

2. Output Configuration:

   • Set the output voltage (VOUT) by adjusting the external resistor divider network connected to the FB pin.
   • The formula to calculate the output voltage is: [ V_ = V_ left(1 + fracright) ] where ( V_ = 0.8V ).

3. Switching Frequency Adjustment:

   • Adjust the switching frequency (fSW) by connecting an external resistor (RT) between the RT/CLK pin and ground.
   • The formula to calculate the switching frequency is: [ f_ = frac{1.2 times 10^6} ] where ( R_T ) is in ohms.

4. Soft-Start Configuration:

   • Connect a capacitor (CSS) between the SS/TRK pin and ground to set the soft-start time.
   • The typical soft-start time is 2.1ms with a 100nF capacitor.

5. Thermal Management:

   • Ensure proper thermal management by placing the device on a PCB with adequate copper area for heat dissipation.
   • Avoid operating the device at temperatures exceeding 125°C to prevent thermal shutdown.

6. Enable/Shutdown Control:

   • Apply a high logic level (≥1.2V) to the EN pin to enable the converter.
   • Apply a low logic level (≤0.4V) to the EN pin to shut down the converter, reducing the quiescent current to 0.1μA.

7. Output Inductor Selection:

   • Choose an inductor with a value that provides stable operation and meets the ripple current requirements.
   • Refer to the datasheet for recommended inductor values based on the desired output current and switching frequency.

8. Output Capacitor Selection:

   • Use a low ESR ceramic capacitor for the output to ensure good transient response and stability.
   • The output capacitor should have a capacitance and ESR that meet the design requirements for the specific application.

By following these instructions, you can effectively configure and use the TPS560430XDBVR in your design.
