TPS62103D datasheet by Texas Instruments

TPS62103D Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the TPS62103D?
  The maximum input voltage that can be applied to the TPS62103D is 18V, but it's recommended to keep it below 15V for optimal performance and reliability.
• How do I ensure the TPS62103D is stable and doesn't oscillate?
  To ensure stability, make sure to follow the recommended layout and component selection guidelines, including the use of a 10uF or larger input capacitor, a 22uF or larger output capacitor, and a minimum of 1uF ceramic capacitor on the VOUT pin.
• What is the minimum input voltage required for the TPS62103D to operate?
  The minimum input voltage required for the TPS62103D to operate is 2.5V, but it's recommended to keep it above 3V for optimal performance and to ensure the output voltage is within regulation.
• Can I use the TPS62103D in a high-temperature environment?
  The TPS62103D is rated for operation up to 125°C, but it's recommended to derate the output current and input voltage as the temperature increases to ensure reliable operation.
• How do I calculate the output voltage of the TPS62103D?
  The output voltage of the TPS62103D can be calculated using the formula: VOUT = 0.8V x (1 + R1/R2), where R1 and R2 are the resistors connected to the FB pin.
