Instructions for TPS62160DSGR

1. Input Voltage Connection:

   • Connect the input voltage between the VIN and GND pins. Ensure the input voltage is within the range of 2.5V to 5.5V.

2. Output Voltage Configuration:

   • The output voltage is fixed at 1.8V. No external resistors are required for setting the output voltage.

3. Power Good Monitoring:

   • Use the PG (Power Good) pin to monitor the status of the output voltage. This pin goes high when the output voltage is within regulation.

4. Enable/Shutdown Control:

   • The EN pin controls the enable/shutdown function. Apply a logic high to enable the device and a logic low to put it into shutdown mode.

5. Capacitor Selection:

   • Choose input and output capacitors based on the recommended values in the datasheet to ensure stability and proper transient response.

6. Thermal Considerations:

   • Ensure adequate thermal management by providing a good thermal path for heat dissipation, especially under high load conditions.

7. Layout Recommendations:

   • Follow the PCB layout guidelines provided in the datasheet to minimize noise and improve performance. Place bypass capacitors close to the IC for optimal results.

8. Operating Temperature Range:

   • Ensure that the operating ambient temperature does not exceed the specified limits to maintain reliability and performance.

Note: Always refer to the latest datasheet from Texas Instruments for the most accurate and detailed information about the TPS62160DSGR.
