TPS72625DCQ datasheet by Texas Instruments

TPS72625DCQ Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the TPS72625DCQ?
  The maximum input voltage that can be applied to the TPS72625DCQ is 5.5V, as specified in the absolute maximum ratings section of the datasheet. Exceeding this voltage can cause damage to the device.
• How do I ensure stability of the output voltage in my design?
  To ensure stability of the output voltage, it is recommended to use a minimum output capacitance of 2.2uF, as specified in the datasheet. Additionally, the output capacitor should have a low equivalent series resistance (ESR) to minimize voltage ripple and ensure stability.
• What is the minimum input capacitance required for the TPS72625DCQ?
  The minimum input capacitance required for the TPS72625DCQ is 1uF, as specified in the datasheet. This capacitance helps to filter out noise and ripple on the input voltage and ensure stable operation of the device.
• Can I use the TPS72625DCQ in a high-temperature environment?
  The TPS72625DCQ is rated for operation up to 125°C, but the device's performance and reliability may degrade at high temperatures. It is recommended to derate the output current and voltage according to the thermal derating curves provided in the datasheet to ensure reliable operation in high-temperature environments.
• How do I calculate the power dissipation of the TPS72625DCQ in my design?
  The power dissipation of the TPS72625DCQ can be calculated using the formula: Pd = (Vin - Vout) x Iout, where Vin is the input voltage, Vout is the output voltage, and Iout is the output current. The thermal resistance of the package (RθJA) should also be considered to ensure that the device does not exceed its maximum junction temperature.
