TPS3306-15DG4 datasheet by Texas Instruments

TPS3306-15DG4 Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the TPS3306-15DG4?
  The maximum input voltage that can be applied to the TPS3306-15DG4 is 18V, but it's recommended to keep it below 15V to ensure reliable operation.
• How do I ensure the TPS3306-15DG4 is stable and doesn't oscillate?
  To ensure stability, make sure to follow the recommended layout and component placement guidelines, use a sufficient output capacitor (at least 10uF), and keep the input capacitor (if used) as close to the VIN pin as possible.
• What is the minimum input voltage required for the TPS3306-15DG4 to operate?
  The minimum input voltage required for the TPS3306-15DG4 to operate is 6.5V, but it's recommended to keep it above 7V for reliable startup and operation.
• Can I use the TPS3306-15DG4 in a high-temperature environment?
  The TPS3306-15DG4 is rated for operation up to 125°C, but it's recommended to derate the output current and input voltage as temperature increases to ensure reliable operation.
• How do I calculate the output voltage ripple of the TPS3306-15DG4?
  The output voltage ripple can be calculated using the formula: ΔVout = (Iout * ESL) / (Cout * fsw), where ESL is the equivalent series inductance of the output capacitor, Cout is the output capacitance, and fsw is the switching frequency.
