TPS61165DRVTG4 datasheet by Texas Instruments

TPS61165DRVTG4 Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal performance?
  Texas Instruments provides a recommended PCB layout in the datasheet, but it's essential to follow good PCB design practices, such as keeping the input and output capacitors close to the IC, using a solid ground plane, and minimizing trace lengths and widths to reduce EMI and noise.
• How do I choose the right input and output capacitors?
  Choose input capacitors with low ESR (Equivalent Series Resistance) and high ripple current rating to handle the input voltage ripple. For output capacitors, select ones with low ESR and high capacitance to ensure stable output voltage. Refer to the datasheet for specific recommendations and calculations.
• What is the maximum ambient temperature for reliable operation?
  The TPS61165DRVTG4 is rated for operation up to 85°C ambient temperature. However, it's essential to consider the junction temperature (TJ) and ensure it stays within the recommended range (–40°C to 150°C) to ensure reliable operation and prevent overheating.
• How do I implement overvoltage protection (OVP) and undervoltage protection (UVP)?
  The TPS61165DRVTG4 has built-in OVP and UVP features. For OVP, the device will shut down if the input voltage exceeds 6.5V. For UVP, the device will shut down if the input voltage falls below 2.5V. You can also implement external OVP and UVP circuits using voltage comparators and resistors to customize the protection thresholds.
• What is the recommended input voltage range for optimal efficiency?
  The recommended input voltage range for optimal efficiency is between 3.5V and 5.5V. Operating outside this range may affect the converter's efficiency and stability.
