TPS2066CDGNR datasheet by Texas Instruments

TPS2066CDGNR Frequently Asked Questions (FAQs)

• What is the maximum capacitance I can use with the TPS2066CDGNR?
  The maximum capacitance depends on the application and the desired performance. However, as a general guideline, TI recommends using capacitors with a capacitance value between 1uF to 10uF. Larger capacitance values may cause stability issues or affect the device's performance.
• How do I ensure the TPS2066CDGNR is stable and doesn't oscillate?
  To ensure stability, follow the layout guidelines in the datasheet, use a low-ESR capacitor, and avoid long traces between the input and output capacitors. Additionally, ensure the input voltage is within the recommended range, and the output current is within the specified limits.
• What is the minimum input voltage required for the TPS2066CDGNR to operate?
  The minimum input voltage required for the TPS2066CDGNR to operate is 2.7V. However, the device can operate down to 2.5V with reduced performance and efficiency.
• Can I use the TPS2066CDGNR in a high-temperature environment?
  The TPS2066CDGNR is rated for operation up to 85°C. However, the device's performance and reliability may degrade at higher temperatures. For high-temperature applications, consider using a device with a higher temperature rating or implementing thermal management techniques.
• How do I calculate the output voltage of the TPS2066CDGNR?
  The output voltage of the TPS2066CDGNR is determined by the resistor divider network connected to the FB pin. Use the formula: Vout = (R1 / R2) * 0.6V, where R1 and R2 are the resistors in the divider network.
