TPS61085DGKRG4 Frequently Asked Questions (FAQs)

  • A 10uF to 22uF X5R or X7R ceramic capacitor is recommended for the input capacitor (CIN). This value provides a good balance between noise filtering and stability.
  • To ensure stability, follow the layout guidelines in the datasheet, keep the input and output capacitors close to the IC, and use a low-ESR output capacitor. Additionally, ensure the feedback resistors (RFBT and RFBG) are properly selected and placed.
  • The maximum input voltage rating for the TPS61085DGKRG4 is 5.5V. Exceeding this voltage may damage the device or affect its performance.
  • The TPS61085DGKRG4 is rated for operation up to 125°C (TJ). However, the device's performance and reliability may degrade at high temperatures. Ensure proper thermal management and consider derating the device's specifications accordingly.
  • The output voltage (VOUT) can be calculated using the formula: VOUT = VREF * (1 + RFBT/RFBG), where VREF is the internal reference voltage (1.2V) and RFBT and RFBG are the feedback resistors.
