Instructions for Use

1. Input Voltage (VIN):

   • The TPS61100PWRG4 operates with an input voltage range of 2.7V to 5.5V. Ensure that the input voltage is within this range to avoid damage or improper operation.

2. Output Voltage (VOUT):

   • The output voltage is fixed at 3.3V. No external components are required to set the output voltage.

3. Quiescent Current (IQ):

   • The quiescent current is typically 1.2μA, which is very low, making the device suitable for battery-powered applications.

4. Efficiency:

   • The efficiency of the TPS61100PWRG4 is high, reaching up to 80% at 1mA and 90% at 100mA. This ensures minimal power loss during operation.

5. Switching Frequency (fSW):

   • The switching frequency is typically 1.5MHz. This high frequency allows for the use of small external components, reducing the overall size of the design.

6. Load Current (IOUT):

   • The maximum load current is 300mA. Ensure that the load does not exceed this limit to prevent overheating or damage.

7. Start-Up Time (tSU):

   • The start-up time is typically 20ms. This is the time it takes for the output voltage to stabilize after the input voltage is applied.

8. Thermal Shutdown (TSD):

   • The device has thermal shutdown protection that activates at approximately 160°C. This feature helps prevent damage due to excessive heat.

9. Package:

   • The TPS61100PWRG4 is available in an 8-pin DSBGA package, which is compact and suitable for space-constrained designs.

Additional Considerations:

• PCB Layout:
  • Proper PCB layout is crucial for optimal performance. Keep the input and output capacitors close to the device to minimize parasitic inductance.
• Capacitors:
  • Use ceramic capacitors with low ESR for both input and output to ensure stability and efficiency.
• Inductor Selection:
  • Choose an inductor with a saturation current rating higher than the maximum load current to avoid inductor saturation, which can lead to reduced efficiency and potential damage.
