TPS61085DGKTG4 datasheet by Texas Instruments

TPS61085DGKTG4 Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the TPS61085DGKTG4?
  The maximum input voltage that can be applied to the TPS61085DGKTG4 is 12V, but it's recommended to keep it below 10V for optimal performance and to prevent damage to the device.
• How do I ensure the stability of the output voltage in my design?
  To ensure the stability of the output voltage, make sure to follow the recommended layout and component placement guidelines, use a sufficient output capacitor with low ESR, and add a feedback capacitor (CFB) as specified in the datasheet.
• What is the minimum input capacitance required for the TPS61085DGKTG4?
  The minimum input capacitance required for the TPS61085DGKTG4 is 10uF, but it's recommended to use a higher value (e.g., 22uF) to ensure stable operation and to filter out input voltage noise.
• Can I use the TPS61085DGKTG4 in a high-temperature environment?
  The TPS61085DGKTG4 is rated for operation up to 125°C, but its performance and reliability may degrade at high temperatures. It's recommended to derate the output current and voltage according to the temperature derating curves provided in the datasheet.
• How do I calculate the output voltage of the TPS61085DGKTG4?
  The output voltage of the TPS61085DGKTG4 can be calculated using the formula: VOUT = VREF x (1 + R1/R2), where VREF is the internal reference voltage (1.2V), R1 is the feedback resistor, and R2 is the divider resistor.
