Instructions for TPS61165DRVR

1. Power Supply Connection:

   • Connect the input voltage (VIN) between 2.5V and 5.5V to the VIN pin.
   • Ensure a stable power supply with appropriate decoupling capacitors near the VIN pin.

2. Output Voltage Configuration:

   • Set the desired output voltage using external resistors connected to the FB pin.
   • Refer to the datasheet for specific resistor values based on required VOUT.

3. Frequency Adjustment:

   • Adjust the switching frequency by connecting an external resistor to the RT pin.
   • Higher resistance increases the switching frequency, which can be set between 1MHz and 2MHz.

4. Efficiency Optimization:

   • For optimal efficiency, ensure that the inductor and capacitor values are chosen according to the recommended guidelines in the datasheet.
   • Place components close to the IC to minimize parasitic effects.

5. Thermal Considerations:

   • Ensure adequate heat dissipation if operating at higher loads or in high ambient temperatures.
   • Use a heatsink or thermal pad as necessary.

6. Shutdown Operation:

   • To place the device in shutdown mode, pull the EN pin low.
   • In this state, the shutdown current is minimized to about 0.1μA.

7. Component Selection:

   • Select inductors and capacitors with low ESR (Equivalent Series Resistance) to improve efficiency and stability.
   • Verify component ratings exceed the maximum expected currents and voltages.

8. PCB Layout:

   • Follow good PCB layout practices to reduce noise and enhance performance.
   • Keep sensitive analog traces away from noisy digital signals and switching nodes.
