Instructions for TPS62202DBVR

1. Power Supply Connection:

   • Connect the input voltage (VIN) between the VIN pin and GND.
   • Ensure the input voltage is within the specified range of 2.5V to 5.5V.

2. Output Configuration:

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

3. Capacitor Selection:

   • Choose input and output capacitors according to the datasheet recommendations to ensure stability.
   • Typically, ceramic capacitors with low ESR are recommended.

4. Inductor Selection:

   • Select an inductor based on the desired output current and ripple requirements.
   • Refer to the datasheet for recommended values.

5. Enable/Shutdown Control:

   • Use the EN pin to control the enable/shutdown function.
   • Apply a logic high (≥1.8V) to enable the device; apply a logic low (<0.4V) to put it into shutdown mode.

6. Thermal Considerations:

   • Ensure adequate heat dissipation if operating at higher loads or ambient temperatures.
   • Consider using a heatsink or placing the device on a PCB with sufficient copper area.

7. Layout Guidelines:

   • Follow good layout practices to minimize noise and improve performance.
   • Keep traces short and direct, especially for power and ground connections.
