Instructions for Using TPS65023RSBT

1. Power Supply:

   • Ensure the input voltage (VIN) is within the range of 2.7V to 5.5V.
   • Use appropriate decoupling capacitors (typically 10μF and 0.1μF) close to the VIN pin to stabilize the input voltage.

2. Output Configuration:

   • VOUT1 and VOUT2 can be adjusted using external resistors. Refer to the datasheet for specific resistor values.
   • Ensure the output capacitors (typically 10μF and 0.1μF) are placed close to the VOUT1 and VOUT2 pins to maintain stability.

3. Shutdown Function:

   • The shutdown function can be activated by pulling the SHDN pin low. This reduces the quiescent current to approximately 1μA.
   • To enable the device, pull the SHDN pin high (to VIN).

4. Thermal Management:

   • Ensure adequate heat dissipation if operating at high currents or in high ambient temperatures.
   • Consider using a heatsink or thermal pad for extended operation under heavy loads.

5. Layout Considerations:

   • Keep the traces from the input and output capacitors as short as possible to minimize inductance and improve transient response.
   • Avoid routing high-frequency signals near the power paths to reduce noise coupling.

6. Storage and Handling:

   • Store the device in a dry environment to prevent moisture damage.
   • Handle with care to avoid static discharge, which can damage the sensitive components.
