TPS61220DCKT datasheet by Texas Instruments

TPS61220DCKT Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the TPS61220DCKT?
  The maximum input voltage that can be applied to the TPS61220DCKT is 12V, but it's recommended to keep it below 10V for optimal performance and to prevent overheating.
• How do I ensure the stability of the output voltage?
  To ensure the stability of the output voltage, it's essential to use a suitable output capacitor with a low equivalent series resistance (ESR) and a sufficient capacitance value. A 10uF ceramic capacitor is recommended.
• What is the minimum input capacitance required for the TPS61220DCKT?
  The minimum input capacitance required for the TPS61220DCKT is 1uF, but it's recommended to use a 2.2uF or larger capacitor to ensure stable operation.
• Can I use the TPS61220DCKT in a high-temperature environment?
  The TPS61220DCKT is rated for operation up to 85°C, but it's recommended to derate the output current and input voltage to prevent overheating and ensure reliable operation.
• How do I calculate the output voltage of the TPS61220DCKT?
  The output voltage of the TPS61220DCKT can be calculated using the formula: Vout = 0.6V + (R1/R2) * (Vfb - 0.6V), where R1 and R2 are the resistors in the feedback network, and Vfb is the feedback voltage.
