TPS72618DCQ datasheet by Texas Instruments

TPS72618DCQ Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the TPS72618DCQ?
  The maximum input voltage that can be applied to the TPS72618DCQ is 5.5V, as specified in the absolute maximum ratings section of the datasheet. Exceeding this voltage can damage 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.
• Can I use the TPS72618DCQ in a high-temperature environment?
  The TPS72618DCQ 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 input voltage according to the thermal derating curves provided in the datasheet.
• How do I calculate the power dissipation of the TPS72618DCQ in my design?
  The power dissipation of the TPS72618DCQ 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 (RθJA) of the package should also be considered to ensure the device does not overheat.
• Can I use the TPS72618DCQ in a low-dropout (LDO) configuration?
  Yes, the TPS72618DCQ can be used in an LDO configuration, but it is not optimized for low-dropout operation. The device has a minimum dropout voltage of 1.4V, which may not be suitable for all LDO applications.
