Instructions for Use:

1. Input Voltage (VIN):

   • Ensure the input voltage is within the specified range (1.8V to 5.5V).
   • Use appropriate input capacitors to stabilize the input voltage.

2. Output Voltage (VOUT):

   • Set the output voltage using the feedback resistor network.
   • Refer to the datasheet for specific resistor values to achieve the desired output voltage.

3. Output Current (IOUT):

   • The device can provide up to 2.0A continuous output current.
   • Ensure proper heat dissipation if operating near the maximum current.

4. Quiescent Current (IQ):

   • The quiescent current is typically 2.9渭A, which helps in reducing power consumption in low-power applications.

5. Shutdown Current (ISD):

   • The shutdown current is typically 0.1渭A, which is useful for battery-powered applications.

6. Efficiency (畏):

   • The typical efficiency is 94% when converting 3.3V to 1.8V at a 1A load.
   • Optimize the layout to minimize parasitic losses and improve efficiency.

7. Switching Frequency (fSW):

   • The switching frequency is fixed at 2.2MHz, which helps in reducing the size of external components.

8. Start-up Time (tSTART):

   • The typical start-up time is 100渭s, which is the time it takes for the output to reach the regulated voltage from 0V.

9. Thermal Shutdown (TSD):

   • The device will shut down if the junction temperature exceeds 160掳C to prevent damage.
   • Ensure adequate cooling or heat sinking for high-power applications.

10. Package:

    • The TPS62175DQCT is available in a DQN-8 package.
    • Follow the recommended PCB layout guidelines to ensure reliable operation and thermal performance.
