TPS2066CDGNR-2 datasheet by Texas Instruments

TPS2066CDGNR-2 Frequently Asked Questions (FAQs)

• What is the maximum capacitance I can use with the TPS2066CDGNR-2?
  The maximum capacitance depends on the application and the desired performance. However, as a general guideline, TI recommends using capacitors with a capacitance of 10uF or less to ensure stability and optimal performance.
• How do I ensure the TPS2066CDGNR-2 is stable and doesn't oscillate?
  To ensure stability, follow the layout guidelines in the datasheet, use a low-ESR capacitor, and add a 1-2kΩ resistor in series with the capacitor to dampen oscillations. Additionally, ensure the input voltage is within the recommended range and the output is properly decoupled.
• What is the minimum input voltage required for the TPS2066CDGNR-2 to operate?
  The minimum input voltage required for the TPS2066CDGNR-2 to operate is 2.7V. However, the device can operate down to 2.5V with reduced performance and efficiency.
• Can I use the TPS2066CDGNR-2 in a high-temperature environment?
  The TPS2066CDGNR-2 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-2?
  The output voltage of the TPS2066CDGNR-2 is determined by the resistor divider network connected to the FB pin. Use the formula: Vout = 1.25V x (R1 + R2) / R2, where R1 and R2 are the resistors in the divider network.
