TPS78618DCQ datasheet by Texas Instruments

TPS78618DCQ Frequently Asked Questions (FAQs)

• What is the maximum input voltage that the TPS78618DCQ can handle?
  The TPS78618DCQ can handle input voltages up to 18V, but it's recommended to keep the input voltage below 15V for optimal performance and to prevent overheating.
• How do I ensure the stability of the output voltage?
  To ensure the stability of the output voltage, it's essential to use a suitable output capacitor with a low equivalent series resistance (ESR) and a sufficient capacitance value. A 10uF ceramic capacitor is a good starting point.
• What is the minimum input capacitance required for the TPS78618DCQ?
  The minimum input capacitance required is 1uF, but it's recommended to use a 4.7uF or 10uF capacitor to ensure stability and reduce input voltage ripple.
• Can I use the TPS78618DCQ in a high-temperature environment?
  The TPS78618DCQ is rated for operation up to 125°C, but it's essential to ensure proper thermal management and heat sinking to prevent overheating. A thermal pad or heat sink is recommended for high-temperature applications.
• How do I calculate the output voltage of the TPS78618DCQ?
  The output voltage of the TPS78618DCQ can be calculated using the formula: Vout = 1.221 * (1 + R1/R2), where R1 and R2 are the resistors used in the feedback network.
